Package installation is broken in Ubuntu 20.24

[mmarinriera]

Hi,

I tried to install the package following the installation instructions on a machine with Ubuntu22.04, with a CUDA capable GPU

I followed the installation steps in the documentation:

conda config --set channel_priority strict
conda create -n decode_env -c turagalab -c pytorch -c conda-forge decode=0.10.2 cudatoolkit=11.3 jupyterlab ipykernel
conda activate decode_env

Installation is successful, however, when I try to import decode with Python, I get this error message:

Python 3.8.19 | packaged by conda-forge | (default, Mar 20 2024, 12:47:35)
[GCC 12.3.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import decode

ImportError: /home/miquel/miniconda3/envs/decode_env/lib/python3.8/site-packages/torch/lib/libtorch_cpu.so: undefined symbol: iJIT_NotifyEvent

Regarding this error message, it has already been reported here, and it seems the solution is to downgrade the mkl package.

conda install -c conda-forge mkl==2024.0

That seemed to solve the issue with decode as well, but I don't know if it will break things at a lower level.

Hope this helps!
