ImportError: Cannot Import Name 'LatentDirichletAllocation' When Importing PCA

I keep getting the error: ImportError: cannot import name 'LatentDirichletAllocation' full traceback: Traceback (most recent call last): File '/home/path/to/file/pca.py', line 7,

Solution 1:

Broken installation.

Try:

For Python 2

pip uninstall scikit-learn
pip install -U scikit-learn==0.20.4

For Python 3

pip3 uninstall scikit-learn
pip3 install -U scikit-learn==0.21.3

Solution 2:

Had this problem, fully uninstalling and re-installing scikit-learn via pip fixed it.
