Unable to import recmetrics

[kleekaai]

I am working on a recommendation engine using collaborative filtering and wanted to try the metrics provided by recmetrics. Here, the error I get trying to import the package (version 0.0.12).

same problem

@kleekaai @Daryaggg check several closed issues about this. The answer follow: If you have used pip install recmetrics in order to install the recmetrics probably your version is not aligned with the updated github repository version given that last realease on pypi is Mar 5, 2019. So, you should install manually recmetrics from github.

@statisticianinstilettos @gregwchase maybe you sould update the release on pypi.

This should be updated now. There is a new release on pypi
