Install issue Ubuntu 18

[maxrohleder]

When installing pyronn like so:

conda env create -n pyronn python=3.6
pip install pyronn

On my system:

• Ubuntu 18
• cuda 10.1 and cudnn8.0.4

I tested the installation:

python -c "import tensorflow as tf;tf.config.list_physical_devices('GPU');import pyronn"

I get the following log/error:

First I had cuda 11.1 installed, but then I got this error:

tensorflow.python.framework.errors_impl.NotFoundError: libcudart.so.10.1: cannot open shared object file: No such file or directory

, which made me assume, that cuda 10.1 is needed by the pyronn-layers.

I suspect, that the layers were built against a specific tf version. This thread suggests that the error code implies this. Which version were the layers build against? (Maybe I am missing something) Could this be taken care of by the setup wheel?

I managed to get it to work by manually downgrading to tensorflow 2.3:

pip install tensorflow==2.3

Maybe this could be integrated into the dependency management of pip?

[csyben]

The pyronn package need to be build against a specific Tensorflow version. The current packages in the pip repository are built against TF 2.3 with CUDA 10 . Currently, there are some problems with the bazel configuration preventing a version for Tensorflow 2.4 with Cuda 11 .

I agree, that this should be inetragted in the dependency management, or at least the supported and working version combinations should be statet in this repository for clarification.

@mareikethies While we are at it: Maybe the windows-binary can be made available via pip as well?

I made my build available here: https://github.com/maxrohleder/win-pyronn

Hi, I encountered the same problem... My GPU on the server is 3090, which strictly requires CUDA11. Is there any way to fix this CUDA version problem on Linux platform? @csyben @maxrohleder Many thanks!

[maxrohleder]

@cocoakang You would have to recompile the layers with your desired cuda version. In theory that's not a problem if you feel comfortable with the tf build pipeline.

I've built a CUDA11 version against TF 2.5, it currently supports only py3.6 (I'm still working on newer versions), but the patches needed by CUDA 11 should be almost the same.
