_pickle.UnpicklingError: invalid load key, 'v'.

[poromaa]

I have installed this in anaconda env. with . ./setup.sh. I also pip installed the other dependencies (fuzzywuzzy etc) needed, added grobid to config.json path etc, setting Keras to theano.

This is what I get stuck on when trying to start ml_worker:

Any ideas

Might bee that I didn't get the data files (according to closed issue): trying that now. Hopefully that solves it. git lfs pull (getting 4.2GB datafiles that I was missing)

[poromaa]

Solved with above.

@poromaa hello, i have the same problem about "_pickle.UnpicklingError: invalid load key, 'v'" , can you discuss how you solved it?

@eng100200 I don't know if you were able to resolve the issues. Just type "git lfs pull" in your git repo.
