__jsonnet not loaded and other warnings

[alikabeer32]

My code:

import sys 

from allennlp.predictors.predictor import Predictor

predictor = Predictor.from_path(
    "https://storage.googleapis.com/allennlp-public-models/bidaf-elmo-model-2018.11.30-charpad.tar.gz"
  )

prediction = predictor.predict(
    passage="Tokyo in Japan. With more than 38 million inhabitants Tokyo is the largest city and has the largest metropolitan area. This city has more inhabitants than the whole country of Canada!", 
    question="How many people live in Tokyo?"
  )
print(prediction["best_span_str"])

Output:

Strongly recommend to set a value, usually the maximum size of the convolutional layer size when using CnnEncoder.

As you can see I am getting the desired answer but it's SUPER slow compared to the demo on the allennlp site. I figure it has something to do with the warnings?

My OS: Windows 10 Python: 3.7.6

PS: I can't seem to be able to install jsonnet at all. Is it even available for windows?

@alikabeer32 we don't officially support windows. Jsonnet has been a sticking point for windows users: https://github.com/allenai/allennlp/issues/612

We'd welcome contributions but are unlikely to prioritize this ourselves.

Is there a workaround ?

@MausamGaurav, @alikabeer32, for now you can pip install jsonnetbin to avoid this warning/error.
