Try to convert the original phi-3-mini-4k and put it in the provided APP, but get the exception.

[scchiustone]

According to the ONNX model provided in the example (microsoft/Phi-3-mini-4k-instruct-onnx/cpu_and_mobile/cpu-int4-rtn-block-32-acc-level-4), following the quantization parameters as described in the folder name (cpu, int4, rtn, block-32, acc-level-4), I attempted to convert the original phi-3-mini-4k model. The model was generated successfully. However, it fails when replacing the original model, regardless of the two conversion methods I used as follows. I found the size of .onnx is different from the provioded version. Are there any suggestions to convert the onnx model to match the official version?

**Method 1:

convert to ONNX

!/data/miniconda/envs/onnx_env/bin/optimum-cli export onnx
--model /data/www/llm_api/dist/{model}/
--task text-generation-with-past ./{model}

quantization

!bash run_quant.sh --model_input=./{model}
--model_output=./{model}/quantized/model
--algorithm=RTN --block_size=32 --accuracy_level=4

**Method 2:

build ONNX

!/data/miniconda/envs/onnx_env/bin/python3 -m onnxruntime_genai.models.builder
-m /data/www/llm_api/dist/{model}/
-o ./{model}/
-p int4
-e cpu
--extra_options int4_block_size=32
--extra_options int4_accuracy_level=4 \

The exception message in Android is as attached.
