OSError on second usage of FastText()

[rodinasophie]

OS: Windows 10 pip installation using Anaconda prompt

Expected Behavior

from torchnlp.word_to_vector import FastText
vectors = FastText()

Once the vectors are downloaded to disk, uploading FastText() model to the memory always works.

Actual Behavior

On the second upload of the model the following error is received:

OSError                                   Traceback (most recent call last)

OSError: [Errno 22] Invalid argument

Steps to Reproduce the Problem

1. Install torchnlp, download .word_vectors_cache:

   from torchnlp.word_to_vector import FastText
   vectors = FastText()

2. Rerun cell/kernels of Jupyter notebook and rerun the cell with code above
