I'm using a Galaxy S9 with 64GB of memory.
package-config.json
{ "device": "android", "model_list": [ { "model": "HF://mlc-ai/Phi-3.5-mini-instruct-q4f16_0-MLC", "estimated_vram_bytes": 4250586449, "model_id": "Phi-3.5-mini-instruct-q4f16_0-MLC", "overrides": { "prefill_chunk_size": 128 } } `
I also noticed there was a crash at runtime because the linker couldn't find the .so output. I renamed the .so to the file name it was looking for and it worked.

Any thoughts?

Hi @mhollis1980, thanks for reporting. we are not able to reproduce this failure so have no immediate ideas. It's also interesting to me why the linker couldn't find the .so output, and it might be helpful for us to dig into it if you would like to share the logs when running mlc_llm package.
