Can't loader text learner on local?

Part 1 (2020)

HI there,

I’m trying to load an exported learner created on Google Colab, for inference on my local machine. This works no problem on Colab, but when I try on my local with this:

learn_inf = load_learner(path/‘ct_pe_whole_model’, cpu=True)

I get the following error:

ModuleNotFoundError Traceback (most recent call last)
in
1 path = Path()
----> 2 learn_inf = load_learner(path/‘ct_pe_whole_model’, cpu=True)

~/anaconda3/envs/fastaiv2/lib/python3.6/site-packages/fastai/learner.py in load_learner(fname, cpu)

844 return result

ModuleNotFoundError: No module named ‘spacy.lookups’

Any idea what the issue might be? For what it’s worth I can do the load_learner function on a vision learner, no problem.

Any help would be much appreciated

fastai depends on a package called spacy (see: https://github.com/fastai/fastai/blob/master/environment.yml)

lookups is a module inside spacy that seems to be missing, it’s a fairly recent addition so my guess would be that your local environment has an older version of spacy installed.

To install the latest version, try:

pip install -U spacy

Thanks for your super fast response. I tried that but no luck. Any other thoughts?
