Hi, I don't know which version of Gensim you are using but I can tell you that in versions >=4 the _l2_norm function has been removed from keyedvectors.py. You can either choose to

• edit your locally downloaded version of Gensim replacing _l2_norm with linalg.norm after adding linalg to the numpy import in the file's imports section
• update your fse with the porting I just made for Gensim >=4 (which also solves this problem) by executing the command

  pip install -U git+https://github.com/AleMuzzi/Fast_Sentence_Embeddings

  works both as an upgrade and as a new version, pull request is waiting for approval (https://github.com/oborchers/Fast_Sentence_Embeddings/pull/65)

Should be fixed in v1.0.0
