Problem with tensorflow in virtual environment

[zoli]

I have an issue with running tensorflow 2.4 in virtual env on workstation with ubuntu 18.04.
The base lambda stack installation is with tensorflow-gpu 1.15. But I need a 2.x tensorflow for testing. So I created a virtual env and installed tensorflow manually with commands:

python3 -m venv lambda-stack-without-tensorflow
source lambda-stack-without-tensorflow/bin/activate
pip install tensorflow-gpu

I have tested it with a minimal example and getting the error:

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

the nvidia setup is:
driver version: 460.39
cuda version: 11.2

What to do? How to get it work?

I also have this issue, using pyenv. Specifically, the system tensorflow does this:

I can see that it s trying to load libcusolver.so.10 instead of 11, but why does libcudnn.so.8 fail?

[alexander.kain]

Moreover, where is libcudnn?

ldconfig -p | grep libcudnn

returns nothing
