Why won't Colab import fpgrowth from mlxtend.frequent_patterns?

Question

When I import mlxtend.frequent_patterns, the function fpgrowth and fpmax are not there. However, they are there if I use Jupyter Notebook in Anaconda Navigator.

Anyone know why Colab will not import?

import pandas as pd

from mlxtend.preprocessing import TransactionEncoder
from mlxtend.frequent_patterns import apriori, fpmax, fpgrowth

ImportError

ImportError: cannot import name 'fpmax' from 'mlxtend.frequent_patterns' (/usr/local/lib/python3.7/dist-packages/mlxtend/frequent_patterns/init.py)

Answer 1

I had the same issue just now. The first solution suggested was to pip the package using this in a code cell:

! pip install mlxtend

However, while that helped with me using apriori, it did not help with fpgrowth. Then, after about three hours, I found a solution. Again, in a code cell, run this:

%pip install mlxtend --upgrade

I'm not sure what the % does that the ! does not.

Answer 2

Colab by default installs some older version of the library.

Try with this specific version. Run the following command: !pip install mlxtend==0.17.0
