pip install not working

Hi David, I'm trying to reinstall the isotree library in order to use the new python functions to export the serialized model.

When i execute

pip install isotree

The following error appears:

$ pip install isotree

Already tried reinstalling cycereal (0.1.3), installed the requirements.txt file in your git code and the same error appears. Any insights?

Do you get the same error if you try Python 3 with pip >= 20?
