Forums - Python version mismatch

Hello,

I'm trying to run snpe-tensorflow-to-dlc in Ubuntu 20.04 LTS (inside Windows Linux Subsystem), but I keep getting the error message that follows:

2021-04-23 17:48:23.460050: W tensorflow/stream_executor/platform/default/dso_loader.cc:60] Could not load dynamic library 'libcudart.so.11.0'; dlerror: libcudart.so.11.0: cannot open shared object file: No such file or directory; LD_LIBRARY_PATH: /mnt/c/DATA/Downloads/SNPE_SDK/snpe-1.49.0.2587/lib/x86_64-linux-clang:/mnt/c/DATA/Downloads/SNPE_SDK/snpe-1.49.0.2587/lib/x86_64-linux-clang:
2021-04-23 17:48:23.462399: I tensorflow/stream_executor/cuda/cudart_stub.cc:29] Ignore above cudart dlerror if you do not have a GPU set up on your machine.
Failed to find necessary python package
Python version mismatch: module was compiled for version 3.6, while the interpreter is running version 3.8.
Please ensure that libDlModelToolsPy3.so is discoverable your PYTHONPATH

For the record, a few points I'd like to anticipate:

• I've manually installed python3.6 (since it does not come pre-installed in Ubuntu 20.04)
• I've set up python3.6 as the default alternative, just like explained in https://developer.qualcomm.com/docs/snpe/setup.html.
• I've installed TensorFlow 2.3 (using pip install)
• When setting up SNPE for TensorFlow, I've used path /home/bodi/.local/lib/python3.6/site-packages/tensorflow to point as TensorFlow installation directory.

Finally, if helps, here's my printenv output:
