pip - Installing specific package version does not work
I was trying to install a library (allennlp) via pip3. But it complained about the PyTorch version. While allennlp requires torch=0.4.0 I have torch=0.4.1:
...
Collecting torch==0.4.0 (from allennlp)
Could not find a version that satisfies the requirement torch==0.4.0 (from allennlp) (from versions: 0.1.2, 0.1.2.post1, 0.4.1)
No matching distribution found for torch==0.4.0 (from allennlp)
Also manually install:
pip3 install torch==0.4.0
Doesn't work either:
Could not find a version that satisfies the requirement torch==0.4.0 (from versions: 0.1.2, 0.1.2.post1, 0.4.1)
No matching distribution found for torch==0.4.0
Same for other versions.
Python is version Python 3.7.0 installed via brew on Mac OS.
I remember that some time ago I was able to switch between version 0.4.0 and 0.3.1 by using pip3 install torch==0.X.X.
How do I solve this?
Answer
allennlp master branch specifies torch>=0.4.0,<0.5.0.
The latest release is v0.6.0 - released only about 3 hours ago - and also specifies this range: https://github.com/allenai/allennlp/blob/v0.6.0/setup.py#L104
It's possible you are using an older release (probably v0.51) which pinned torch==0.4.0: https://github.com/allenai/allennlp/blob/v0.5.1/setup.py#L104
torch have not yet released a v0.4.0 distribution supporting 3.7 to PyPI: there are wheels for CPython 2.7, 3.5, and 3.6. No source distributions.
allennlp==0.6.0 and torch==0.4.1post2 should work on Python 3.7. I was able to resolve the (considerably large) dependency tree on a linux/Python 3.7.0 runtime using my project johnnydep:
$ johnnydep allennlp --fields name version_latest_in_spec
name version_latest_in_spec
