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

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 commented

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.
