ImportError: cannot import name 'appengine' from 'requests.packages.urllib3.contrib'
set up environment mostly according to the tutorial:
conda create -n mocca python=3.9
conda activate mocca
pip install git+https://github.com/HaasCP/mocca@master
pip3 install -U datapane==0.14
pip install notebook
while going through the cyanation tutorial, I use this code:
# folders handling

And I get this error:

I'm not sure where the dependencies broke, but I was unable to do pip install mocca because the requirements in the pip package still uses sklearn rather than scikit-learn, so I had to improvise. I am working on Windows.
Edit: To clarify, the HplcDadCampaign and other classes used for analysis works fine, it's just report that is the problem.
It looks like importing datapane (which is the package used to generate the reports) is causing an ImportError when importing appengine. Could you try updating the requests / urllib3 packages? I used the same commands you had above and I was able to successfully import the package. I have requests version 2.25.1 and urllib3 1.26.5.
in the earlier post i had requests==2.31.0 and urllib3==2.1.0.
upgrading to requests==2.25.1 and urllib3==1.26.5 worked, thanks!

Since this repo will be deprecated soon, we will not fix it properly but leave this issue open for reference.
