本文介绍了一个使用Python脚本将ONNX模型转换为MNN格式的问题案例。主要探讨了转换过程中出现的警告信息及错误，并给出了具体的错误日志。错误包括Python指令的警告和protobuf解析错误。

python mnn1.1.4

cmd_dtr 是转换指令

注释的代码是调用MNNConvert.exe进行转换，这个是1.0.0版本的mnn，可以用

import os


def onnx2mnn(onnx_name,mnnname):

    cmd_dtr="python -m MNN.tools.mnnconvert -f ONNX --modelFile "+onnx_name+"  --MNNModel "+mnnname+" --bizCode MNN"
    print(cmd_dtr)
    # cmd_dtr=r"E:\MNN\MNN\Windows\MNN_Windows_tools\MNNConvert -f ONNX --modelFile "+onnx_name+" --MNNModel "+mnnname+" --bizCode MNN"
    res_str= os.popen(cmd_dtr).read()

    print(res_str)
    if "Converted Done" in res_str:
        print("Converted ok")

python开头的是python指令，现在是报错:
