Trouble installing Python version

[jingxinfu]

Thank you for creating this fantastic tool. I attempted to download it by following the provided documentation, but I encountered the following error:

It could be that the discover package is not available for your platform. Can you tell me which Python version, operating system, CPU you are using?

thanks for the reply. below are the detail infos:

• Python 3.9.19
• OS: macOS
• CPU: Apple M4

Indeed there were no packages for Apple Silicon CPUs yet. I uploaded them to the repository now, so you should be able to install discover in your environment. Note that these packages are generated using an automated build system. I have not tested them on an M4 processor, so do let me know whether they work for you.

I was able to install the package, but importing it results in following errors:

Library not loaded: @rpath/libgfortran.5.dylib

Looks like there have been more recent reports of issues with conda packages and libgfortran on macOS:

• BUG: Duplicate RPATH's on macOS>=15.4 causing installation failures conda/conda-build#5671
• Numpy import error when using conda-forge build of numpy 2.2.3 // no issue with pip conda-forge/numpy-feedstock#347
• duplicate LD_RPATH for numpy on MacOS 15.4 prefix-dev/pixi#3479

One fix that seems to work for some people is to make sure that the version of the libgfortran5 package is >= 14. At the moment this version is only available from the conda-forge channel, not from pkgs/main.

What you may try is to create a completely new environment (based on conda-forge packages). Then run python from this environment and see whether this fixes the issue:

conda create -n discover_env -c conda-forge -c https://ccb.nki.nl/software/discover/repos/conda discover
conda activate discover_env
