Run the function `interpreter->AllocateTensors()` unsuccess #30

jiwenfei · 2023-01-31T04:18:02Z

I want to launch the movenet model at my board esp32s3 korvo-2.

And i firstly change the pretrained ftfile to cc file by using the code

MODEL_TFLITE='/content/model.tflite'
MODEL_TFLITE_MICRO='/content/movenetmodel.cc'
# Install xxd if it is not available
# !apt-get update && apt-get -qq install xxd
# Convert to a C source file, i.e, a TensorFlow Lite for Microcontrollers model
!xxd -i {MODEL_TFLITE} > {MODEL_TFLITE_MICRO}
# Update variable names
REPLACE_TEXT = MODEL_TFLITE.replace('/', '_').replace('.', '_')
!sed -i 's/'{REPLACE_TEXT}'/g_model/g' {MODEL_TFLITE_MICRO}

and my code is:

extern "C" void app_main() {
  printf("start !!\n");
  
  const tflite::Model* model = ::tflite::GetModel(g_modelerererer);
  if (model->version() != TFLITE_SCHEMA_VERSION) {
      printf("load model error!\n");
  }
  printf("model load success !!\n");
  tflite::AllOpsResolver resolver;
  const int tensor_arena_size = 2028784;
  static uint8_t *tensor_arena;
    if (tensor_arena == NULL) {
    tensor_arena = (uint8_t *) heap_caps_malloc(tensor_arena_size, MALLOC_CAP_SPIRAM);
  }
  if (tensor_arena == NULL) {
    printf("Couldn't allocate memory of %d bytes\n", tensor_arena_size);
    return;
  }
  printf("array init success !!\n");
  tflite::MicroInterpreter* interpreter = nullptr;
  static tflite::MicroInterpreter static_interpreter(model, resolver, tensor_arena,
                                     tensor_arena_size);
  interpreter = &static_interpreter;
  printf("interpreter init success !!\n");
  TfLiteStatus allocate_status = interpreter->AllocateTensors();
  if (allocate_status != kTfLiteOk) {
    MicroPrintf("AllocateTensors() failed");
    return;
  }
  printf("tensor init success !!\n");
  TfLiteTensor* input = interpreter->input(0);
  printf("input->dims->size=%d,input->dims->data={%d,%d}\n",input->dims->size,
        input->dims->data[0],input->dims->data[1]);
  printf("check success!\n");
  
}

and monitor show

Hi @jiwenfei

Do existing examples run fine of you?
Can you please enable gdb stub and share backtrace output? Need to know where exactly the crash is happening.
Have you designed your op_resolver properly? With structure size = number of OP?
e.g,

https://github.com/espressif/tflite-micro-esp-examples/blob/72f2c9914561497cbd6ab5d951a83e2462840596/examples/person_detection/main/main_functions.cc#L85-L90

jiwenfei · 2023-01-31T05:21:37Z

@vikramdattu
1.the existing examples are ok,
3. I used the code tflite::AllOpsResolver resolver; to import ops.

vikramdattu · 2023-01-31T05:46:39Z

Hi @jiwenfei can you try the following:

Increase main task stack from menuconfig to some large number, (by default it is 3K).
Keep gdb stub enabled to catch the reset point.
Alternately, you may offload the function to different task with higher stack like this: https://github.com/espressif/tflite-micro-esp-examples/blob/72f2c9914561497cbd6ab5d951a83e2462840596/examples/person_detection/main/main.cc#L42

@vikramdattu
the gdb stub msg is

Hi @jiwenfei can you try the following:

Increase main task stack from menuconfig to some large number, (by default it is 3K).

Keep gdb stub enabled to catch the reset point.

Alternately, you may offload the function to different task with higher stack like this: https://github.com/espressif/tflite-micro-esp-examples/blob/72f2c9914561497cbd6ab5d951a83e2462840596/examples/person_detection/main/main.cc#L42

I have written the code as you note, but there is nothing changed.

vikramdattu · 2023-01-31T13:37:05Z

Hi @jiwenfei I converted the above model and tried to run. I am getting similar issues if not exact.

There are few issues:

Below lines are illegal as these try to modify data from const array(the model data):
https://github.com/espressif/tflite-micro-esp-examples/blob/388c558a2174deb7d2c83efd244e2b4d30636edf/components/tflite-lib/tensorflow/lite/micro/kernels/gather_nd.cc#L93-L100

Please comment those out before running the code.

After this the code will run but when you invoke the function you get type not supported errors:

Input type UINT8 (3) not supported.

Type 'INT32' is not supported by FLOOR_DIV.
Node FLOOR_DIV (number 90) failed to invoke with status 1

The model is not compatible with tflite-micro and must be outdated!

What you can do is quantise the model yourself with following options and try:

def representative_dataset():
  for i in range(100):
    yield [tf.random.uniform(shape=[1,1,192,192], minval=.0, maxval=1.)]

# make a converter object from the saved tensorflow file
converter = tf.compat.v1.lite.TFLiteConverter.from_saved_model('person_det_opt.pb/' #TensorFlow freezegraph .pb model file
                                                      )
# tell converter which type of optimization techniques to use
converter.optimizations = [tf.lite.Optimize.DEFAULT]
# to view the best option for optimization read documentation of tflite about optimization
# go to this link https://www.tensorflow.org/lite/guide/get_started#4_optimize_your_model_optional

# This is must when converting with `TFLITE_BUILTINS_INT8`
converter.representative_dataset = representative_dataset
converter.target_spec.supported_ops = [tf.lite.OpsSet.TFLITE_BUILTINS_INT8, tf.lite.OpsSet.SELECT_TF_OPS]
converter.inference_input_type = tf.int8
converter.inference_output_type = tf.int8

jiwenfei · 2023-02-01T09:19:42Z

@vikramdattu
The tf model movenet have been converted into micro-tffile as your code, like this:

def representative_dataset():
  for i in range(100):
    # tf.cast(tf.squeeze(tf.random_uniform((1, 1)))*2, dtype=tf.int32)
    yield [tf.cast(tf.random.uniform(shape=[1,192,192,3], minval=.0, maxval=1.)*255,dtype=tf.int32)]

# make a converter object from the saved tensorflow file
converter = tf.compat.v1.lite.TFLiteConverter.from_saved_model('/content/4/' #TensorFlow freezegraph .pb model file
                                                      )
# tell converter which type of optimization techniques to use
converter.optimizations = [tf.lite.Optimize.DEFAULT]
# to view the best option for optimization read documentation of tflite about optimization
# go to this link https://www.tensorflow.org/lite/guide/get_started#4_optimize_your_model_optional

# This is must when converting with `TFLITE_BUILTINS_INT8`
converter.representative_dataset = representative_dataset
converter.target_spec.supported_ops = [tf.lite.OpsSet.TFLITE_BUILTINS_INT8, tf.lite.OpsSet.SELECT_TF_OPS]
converter.inference_input_type = tf.int8
converter.inference_output_type = tf.int8
model_tflite = converter.convert()

# Save the model to disk
open('model.tflite', "wb").write(model_tflite)

But it also showed errors like this

Hi @jiwenfei

https://github.com/espressif/tflite-micro-esp-examples/blob/388c558a2174deb7d2c83efd244e2b4d30636edf/components/tflite-lib/tensorflow/lite/micro/kernels/floor_div.cc#L112-L122

This particular OP is not implemented by tflite-micro in other data types. Probably, nobody came across it.

Maybe just calling with data type int32_t will work. Please try.

  switch (input1->type) {
    case kTfLiteFloat32: {
      return EvalFloorDiv<float>(context, input1, input2, output);
    }
    case kTfLiteInt32: {
      return EvalFloorDiv<int>(context, input1, input2, output);
    }
    default: {
      MicroPrintf("Type '%s' is not supported by FLOOR_DIV.",
                  TfLiteTypeGetName(input1->type));
      return kTfLiteError;
    }
  }

You may want to contribute this back if it works to the repo: https://github.com/tensorflow/tflite-micro

For stack overflow error, please increase the task stack and check.

jiwenfei · 2023-02-01T10:27:36Z

@vikramdattu
Ths! It newly shows that The SUB op not supported INT32, I will do some change as you note above methods

It works well, after I update SUB and FLOOR_DIV ops implements as you said.

vikramdattu · 2023-02-02T05:46:50Z

Hi @jiwenfei does that mean, you are getting expected outputs as well? What FPS do you get with the solution?

jiwenfei · 2023-02-02T07:33:33Z

Hi @jiwenfei does that mean, you are getting expected outputs as well? What FPS do you get with the solution?
Yes,
model init time:105ms,
and model invoke time : 3007ms.

So I want connect two esp32 modules in seris.
The first one is used to detect for good person imgage,
and the last is used to dectect keypoint for body

jiwenfei · 2023-02-02T10:35:55Z

@vikramdattu Can you give me some suggestion to cutdown the invoke time for this movenet mobile?

vikramdattu · 2023-02-03T05:42:01Z

Hi @jiwenfei as I can see esp-nn has already has added about 10x improvements. Below flag can be removed to see raw performance:
https://github.com/espressif/tflite-micro-esp-examples/blob/388c558a2174deb7d2c83efd244e2b4d30636edf/components/tflite-lib/CMakeLists.txt#L92

Few things

I have seen that the memory requirements and flash requirements for this model are quite huge. (~2MB each). If you could modify the model and use a lighter one, it would save both in flash and performance. (I would recommend a model which has size around 1 MB or less for smooth functional. Even that should be good enough for a micro-controller).
I have not checked for if more performance could be sqeezed "for this specific model" (Not checked for which specific layer is eating most of the time etc.), since I believe the optimisations are already top notch and the exercise might not lead to huge improvements if any. I might be wrong.

Also, I haven't tried to quantise the float model from here myself and have used the quantized int8 model provided by google (which might be optimised long time in the past). Maybe manually quantising this now, might result in better optimised model?

Hope this helps. Let me know if I can help you in the process.

jiwenfei · 2023-02-03T06:05:12Z

OK，I will think and try.

vikramdattu · 2023-02-03T06:06:19Z

@jiwenfei in addition to above comment, can you please make sure:

Your module is running in Octal mode if that's available? For flash as well as RAM?
Check if Data Cache is set to 64KB and I cache is set to 32KB?

Basically, let's check if the chip is running into the full performance mode.

jiwenfei · 2023-02-03T06:57:00Z

Your module is running in Octal mode if that's available? For flash as well as RAM?

NOT Available while it is Octal mode

jiwenfei · 2023-02-15T09:19:14Z

Hi @vikramdattu
Now, I have some new questions:
1.While the input data is from the camera on the board, the function interpreter->Invoke() sometimes throw errors like this:

E (222810) task_wdt: Task watchdog got triggered. The following tasks did not reset the watchdog in time:
E (222810) task_wdt:  - IDLE (CPU 0)

@jiwenfei one loop of the function it seems is larger than the WDT configured and hence causing the issue.
Can you please increase this value to accommodate the whole run time? (idf.py menuconfig > component config > freeRTOS > Task watchdog timeout).
Also, are you using the display? If not, you may want to remove the display code.

jiwenfei · 2023-02-16T04:01:51Z

@vikramdattu
After I set a new number of watchdog timeout, It says that tensorlite's unpack op is not right, the terminal msg is:

Hi @jiwenfei I missed your last message!

Do you still face the issues?

By the way, the gather_nd issue is now fixed on the latest sync. So, you may want to update to it by doing git pull --rebase and continue your development.

vikramdattu · 2023-03-06T11:35:52Z

Hi @jiwenfei I have done changes in the following patch. Please check if you've done the similar:
add_unsupported_ops.patch

The code was running fine for multiple iterations. I am using IDF branch release/v4.4. Also, if the issue persists, would you try the model on tflite-micro - x86?

The crash above seems something which you should raise on tflite-micro site directly as it looks to be coming from common code. Would you please raise the issue there? This would yield some quick fix.

@vikramdattu The last problem is caused by drawing pictures, like this ```
fb_gfx_fillRect (camera_fb_t *fb, int32_t x, int32_t y, int32_t w, int32_t h, uint32_t color);

vikramdattu · 2023-03-24T06:19:16Z

@jiwenfei that could mean that the camera_fb frame is smaller in size that that of width height provided to the function and it is trying to access outside buffer boundary.
Did you fix this now? Please check on this.

jiwenfei · 2023-03-24T06:27:57Z

The result which run on colab coded by python is different from that run in esp32s3.
And I run the code in esp32s3 as follow:
1.change an image to hpp file

import cv2
import numpy
import tensorflow as tf
image_path='/content/data/tang/1678084611419.jpg'
image = tf.io.read_file(image_path)
image = tf.compat.v1.image.decode_jpeg(image )
image=image.numpy()
h,w,c=image.shape
with open('images.hpp', 'w') as file:
        file.write('#pragma once\n'
                   '#include <stdint.h>\n\n'
                   f'#define IMAGE_HEIGHT {h}\n'
                   f'#define IMAGE_WIDTH {w}\n'
                   f'#define IMAGE_CHANNEL {c}\n\n'
                   'const static uint8_t IMAGE_ELEMENT[] = {\n')

        image = numpy.reshape(image, (-1,))
        for i, element in enumerate(image[:-1], 1):
            if i == 1:
                file.write('    ')

            file.write(f'{element}, ')

            if i % 32 == 0:
                file.write('\n    ')
        file.write(f'{image[-1]}')
        file.write('};\n')

run tf lite infer at esp32 by using the image hpp

input = interpreter->input(0);
  printf("input->dims->size=%d,input->dims->data={%d,%d}\n",input->dims->size,
        input->dims->data[0],input->dims->data[1]);
  printf("check success!\n");
  
 
  for (int i = 0; i < 192 * 192*3; i++) {
    input->data.i32[i] = IMAGE_ELEMENT[i];
  }
  printf("input data init success\n");
  start_time = esp_timer_get_time();
  if (kTfLiteOk != interpreter->Invoke()) {
    printf("Invoke failed.\n");
     
  }
  total_time = (esp_timer_get_time() - start_time);
  printf("Invoke success.time  %lld\n",total_time/1000);
  TfLiteTensor* output = interpreter->output(0);
  printf("output->dims->size=%d,output->dims->data={%d,%d}\n",input->dims->size,
        output->dims->data[0],output->dims->data[1]);

  for(uint8_t i=0;i<17*3;i+=3){
    int x = output->data.int8[i];
    int y = output->data.int8[i+1];
    printf("point[%d],x=%d,y=%d,score=%d\n",i/3,(x),(y),( output->data.int8[i+2]));
 
  }

the python code is

import tensorflow as tf
import cv2
import matplotlib.pyplot as plt
interpreter = tf.lite.Interpreter(model_path="/content/model.tflite")
interpreter.allocate_tensors()
input_details = interpreter.get_input_details()
output_details = interpreter.get_output_details()

image = tf.io.read_file(image_path)
image = tf.compat.v1.image.decode_jpeg(image)

image = tf.expand_dims(image, axis=0)
  # Resize and pad the image to keep the aspect ratio and fit the expected size.

print(keypoints_with_scores)

the result in esp32 is:

Hi @jiwenfei

Does disabling esp_nn give the same results? // you can do this via menuconfig > ESP_NN
Can you confirm the model input is same in case of both collar and ESP32?
Below steps looks wrong to me:

  for (int i = 0; i < 192 * 192*3; i++) {
    input->data.i32[i] = IMAGE_ELEMENT[i];
  }

I think the input to be fed is expected to i8[]?
Also, please check if you need quantisation on input. ( If yes, something like input->data.i8[i] = IMAGE_ELEMENT[I] - 128; will fix it)

jiwenfei · 2023-03-24T06:35:59Z

@jiwenfei that could mean that the camera_fb frame is smaller in size that that of width height provided to the function and it is trying to access outside buffer boundary. Did you fix this now? Please check on this.

Yes, I have modified code that ,It because of out of bound.

Hey, @jiwenfei this is because unoptimised kernels take huge time to process and hence task watchdog timer which is by default set to 5 seconds gets triggered.
You can either ignore that or increase FreeRTOS task watchdog time to a higher number, say 15 seconds.

vikramdattu · 2023-06-14T05:40:51Z

Hello @jiwenfei are you still looking into the issue or are willing to test the same?
Please apply patch from following comment on ESP-NN and check if mismatch issue goes away: espressif/esp-nn#5 (comment)

jiwenfei · 2023-06-19T07:52:47Z

Because of low image quality and much work need to do for image quality correction, so we switched to a new solution by using rv1126 board

vikramdattu · 2023-06-19T08:59:44Z

@jiwenfei thanks for the heads up. For my reference, can you please share information about which camera did you use with ESP32-S3 and in which mode? (Resolution and the JPEG quality used, if images were captures as JPEG).
