how are you installing tpot?

When creating a new environment with anaconda, and installing with pip, I'm able to install the package very quickly with

conda create -n myenv python
conda activate myenv
pip install tpot

Note that this installs the latest Python version, which breaks the current version tpot (#1327), but PR #1331 fixes this. In the meantime, manually installing the fix or using an older version of python should work.

ImportError: cannot import name 'get_scorer_names' from 'sklearn.metrics'

This could be due to an old version of scikit learn being used. I updated the minimum requirements for TPOT. Try updating your sklearn version to the latest and let us know if that resolved the issue.
