Failed to install with pip about argos-translate

[PJ-Finlay]

It looks like pip is having a hard time installing SentencePiece from PyPI. Try:

python3 --version
python3 -m pip install --upgrade pip
python3 -m pip install argostranslate

I've also encountered this error, strange:

On the other hand, 0.1.94 works fine (?)

pip install sentencepiece==0.1.94
