Error when running the colab notebook #148

Closed Tooba-ts1700550 closed 3 years ago

Tooba-ts1700550 commented 3 years ago

I get the following error when running the second line in colab notebook:

!capreolus rank.searcheval with benchmark.name=nf searcher.name=BM25 searcher.index.stemmer=porter searcher.b=0.8 ImportError: cannot import name '_ColumnEntity' from 'sqlalchemy.orm.query' (/usr/local/lib/python3.7/dist-packages/sqlalchemy/orm/query.py)

Please help. This is after Capreolus installs successfully.

You should be able to fix this error by downgrading sqlalchemy after installing Capreolus: pip install sqlalchemy==1.3.24

The issue is that a new, incompatible sqlalchemy version was recently released. This is fixed in git, and we'll make a new pypi release soon that avoids the need for manually downgrading.

thank you, your solution fixed the issue.
