Could not find a version that satisfies the requirement torch

[joseakamaru]

Describe the bug I have followed the installation instructions mentioned on the Github Readme and from the Allenai Website, but I always received the following prompt on the command line.

ERROR: Could not find a version that satisfies the requirement torch<1.2,>=0.4.1 (from allennlp) (from versions: 0.1.2, 0.1.2.post1, 0.1.2.post2) ERROR: No matching distribution found for torch<1.2,>=0.4.1 (from allennlp)

I have tried installing the conda environment, but that has failed also. I received the same error regardless of the method of installation.

To Reproduce Steps to reproduce the behavior

1. Install Anaconda and ensure that its part of your PATH
2. From the command prompt, run the following conda create -n allennlp python=3.6
3. Activate conda enviroment via 'conda activate allennlp'
4. Then install the allennlp running the following on the command prompt: pip install allennlp
5. See error

Expected behavior I expected a clean download and install of the allennlp.

System (please complete the following information):

• OS: Windows 10 Pro
• Python version: Python 3.6.9 and Python 3.7.3
• AllenNLP version: trying to install from master
• PyTorch version: (if you installed it yourself)

Additional context Add any other context about the problem here.

technically allennlp is not supported on windows. I suspect that's a big part of your problem. I would try installing torch first separately. if that works, then you should be able to install allennlp afterward.

I was able to determine the issue with the import Torch. I needed to install the package Cuda on my device, which then enables the installation of Torch. After installing Torch, I still have the same error prompt:

ERROR: Could not find a version that satisfies the requirement torch<1.2,>=0.4.1 (from allennlp) (from versions: 0.1.2, 0.1.2.post1, 0.1.2.post2) ERROR: No matching distribution found for torch<1.2,>=0.4.1 (from allennlp)

Even though I have Torch (1.2.0) and torchvision (0.4.0) installed.

the pip-installable version of allennlp doesn't work with pytorch 1.2. (you can see it wants bounds torch<1.2,>=0.4.1) you need to use e.g. 1.1.

the next release of allennlp will work with pytorch 1.2

Thanks! That helped a lot
