ModuleNotFoundError: No module named '_dnnc'

Hi, After installing deepC, I am trying to test if it is working. I see the following error. Any suggestion regarding this error? Environment: Mac OS

(base) MU00158281X:~ mmoh0027$ python -c "import deepC.dnnc as dc; print(dc.arange(5));"

It should not occur, if you used

python3 setup.py install

Workaround 1: run sudo python3 setup.py install

Workaround 1: set environmental variable PYTHONPATH, e.g. export PYTHONPATH=<deepC-root-dir>/

@srohit0 Hi Rohit, Thanks for your suggestion. I have used pip install deepC that all your tutorials and videos suggested. It always said 'deepC.dnnc is not found'. I manually checked the installation and it was not there. Then cloned the git repo and I used all your suggested options but no luck, same error. I have also tried the suggested way provided at the top of the setup.py file how to run this script: python setup.py bdist_wheel how to test install: python -m pip install ~/dnnc/master/deepC/dist/dnnc-0.1-py3-none-any.whl --root pip_install_test

So, I haven't been able to use deepC anyway. Am I missing something?

Few developers have used MAC in the past successfully.

You can use cainvas.ai-tech.systems to avoid installation.

We'd be glad to help out, if you're open.

Hi, I have developed a tensorflow model and convertred it to onnx. Now I need to port it to micro controller. I need to convert it to c. I am using windows 10. I tried these codes and I am also getting the "ModuleNotFoundError: No module named '_dnnc'. Can you please help me.

[srohit0]

Sure, we'd be happy to help if you can share your screen to resolve the issue.

Alternatively, you can use cainvas.ai-tech.systems to avoid installation and the issue altogether.

Thanks. Please reach out to hi @ ai-techayatems .c0m for further installation support.

[AnanyaPadmadharan]

Can you please describe the steps to be followed to convert an onnx model( converted from tensorflow) to c which can be deployed on microcontroller (windows environment)

You're one of the few reporting this. Unless we see the issue in action, there are no steps we can recommend.
