TypeError: Client.__init__() got an unexpected keyword argument 'proxies'

[gregpr07]

Confirm this is an issue with the Python library and not an underlying OpenAI API

• This is an issue with the Python library

Describe the bug

SyncHttpxClientWrapper has hard coded proxies but it no longer exists in httpx 0.28

To Reproduce

1. pip install openai
2. the bug appears when calling openai.OpenAI(**client_params, **sync_specific)

Same issue:

• Use of proxies kwarg in httpx==0.28.0 #1902

[dgellow]

Thanks for the report, as mentioned by @simonw this is similar to #1902 and will be fixed by #1903. I will close this issue as duplicate.

What is the solution now？

[3218923350]

I directly commented out the proxies in the constructor of SyncHttpxClientWrapper in openai/_base_client.py, and it works properly now.

[RobertCraigie]

Updating to the latest openai version will fix the issue.

[bsenftner]

Is this supposed to be fixed? I'm still seeing the 'proxies' issue when trying to update a container at AWS. I've updated to OpenAI 1.55.3, and my code does not use Httpx at all. I'm using the Async client.

client = AsyncOpenAI( api_key=get_settings().OPENAI_API_KEY, )
File "/home/app/venv/lib/python3.9/site-packages/openai/_client.py", line 337, in __init__
super().__init__(
File "/home/app/venv/lib/python3.9/site-packages/openai/_base_client.py", line 1428, in __init__
self._client = http_client or AsyncHttpxClientWrapper(
File "/home/app/venv/lib/python3.9/site-packages/openai/_base_client.py", line 1325, in __init__
super().__init__(**kwargs)
TypeError: __init__() got an unexpected keyword argument 'proxies'

[RobertCraigie]

Hey @bsenftner are you sure you're on the latest version? You can verify by running this command

python -c 'import openai; print(openai.__version__)'

[bsenftner]

Yes I am on the latest version. I log the OpenAI version via "RUN pip3 show openai" during container build, as well as

import openai
log.info(f"LOOOOOOK: openai.__version__ {openai.__version__}")

from openai import AsyncOpenAI
#
client = AsyncOpenAI(
    api_key=get_settings().OPENAI_API_KEY,
)

when my app starts up and both confirm version 1.55.3.

@bsenftner Could you try to pin httpx to 0.27.2? That wouldn't explain why it doesn't work in your environment but would unblock you

[bsenftner]

@dgellow I'm starting to think my pipeline may have some additional issue. I tried your suggestion of pinning httpx to 0.27.2 yesterday, and still saw the issue. Since that time my AWS specialist has been double checking things, so I'm trying the pinning of httpx to 0.27.2 again and will report back.

No one else is seeing this, still, I guess?

[bsenftner]

Looks like the pinning is working now. My local container builds have been working the entire time, so I suspect I need to examine my build & deploy pipeline at AWS. If it's only me, then it's only my issue.

[dgellow]

Based on the symptoms you're describing I suspect your docker image is using an old cache (i.e one of the layer comes from a cache instead of being rebuilt). But yes, so far you have been the only one reporting that issue. Glad you were able to make the pinning work :)

[ericzhou571]

Updating to the latest openai version will fix the issue.

We have already updated OpenAI using pip install openai==1.56.0. However, with httpx==0.28.0, the issue (TypeError: Client.__init__() got an unexpected keyword argument 'proxies') still persists.

We resolved it by downgrading httpx to version 0.27.x. To isolate the environment, we created a new Conda environment and reinstalled both httpx and openai using the command:

pip install openai "httpx[socks]"

This installed the latest OpenAI version (1.56.0) as expected, but it still installed httpx==0.28.0 despite the requirements.lock file in your repository specifying httpx==0.25.2. Could you clarify why pip's dependency resolution process doesn’t respect the version specified in requirements.lock?

openai-python/requirements.lock

Line 29 in 534d6c5

httpx==0.25.2

[RobertCraigie]

@ericzhou571 the requirements.lock file is only for internal usage, we wouldn't want to impose direct pins for all our dependencies as that would cause so many version conflicts.

Are you sure you're using the latest version? What does running this output?

import openai
print(openai.__version__)

[goy-jin]

我在 openai/_base_client.py 的 SyncHttpxClientWrapper 的构造函数中直接注释掉了代理，现在它现在可以正常工作了。

我没有找到这个

print(openai.version)
1.56.1

[redhatpeter]

Has this issue been fixed? still happening to me.
python -c 'import openai; print(openai.version)'
1.56.2
TypeError: Client.init() got an unexpected keyword argument 'proxies'
is there any workaround solution?

[dgellow]

@redhatpeter A workaround is to pin the httpx version to 0.27.2, you can see it described here: #1902 (comment)
