try in a new conda env:

same error happens again.

• deleting and resetting a new conda environment from start is not working either.
• Trying from start with anaconda3 or miniconda reprodruces the same fail.
• trying to build a docker image locally with the procedure of the readme fails with the same error:

docker build failed with 1 code

Conclusion: There is something which either I do not understand in the install procedure or which is not really reproducible.
