Dear all,

unfortunately, I have massive problems while installing/using the standalone version of sen2cor 2.11. I get lots of messages like “no module named ‘skimage’” (this happened for at least 5 other packages, too) and code errors (I assume Python 2.x was used?!). Is there anything I did wrong in the installation process or are these errors bugs you need to solve?

I appreciate any helping comments! Thank you!


Additional info: I use Python 3.11. Currently going back to Python 3.10 to see if this changes anything. I’ll keep you posted.

@Amalia-Castro-Gomez can you please take a look?

I still could not solve the problem on my own. The change to Python 3.10 didn’t help.
Currently, I can’t fix the error " import topographicshadows_cython_03
ImportError: DLL load failed while importing topographicshadows_cython_03", which is part of
Any advice on this?


I’m sorry but I’m also not familiar with sen2cor.

Maybe @bdpg can help?

I need some more details for trying to help.
On which platform do you like to install Sen2Cor? Windows, Linux or MAC? Information about release/version could also be helpful.
How do you try to install Sen2Cor? Steps, commands, …?

Sen2Cor 2.11 installation was going without problems for me, both on Windows (MS Windows 10 Enterprise) and on Linux (Red Hat Enterprise Linux Workstation version 7.9).

Kind regards

We will look into it too and report back, thanks for your patience !

Hi everyone,

I solved it by myself: I called the wrong L2A_Process (.py instead of the batch file). Sorry for the inconvenience and thank you very much for helping me!
