Describe the bug
UnpicklingError: pickle data was truncated

I got the above error while executing this:
sfd = SequenceTagger.load('frame-fast') # semantic frame detection

UnpicklingError Traceback (most recent call last)

Environment (please complete the following information):

• OS [e.g. iOS, Linux]: Ubuntu 16.04

Additional context
I have 16 gb of RAM. I tried emptying the RAM and then rerunning it but no luck.

Help needed.

Could it be that you ran out of disk space when downloading the model?
