Haystack: Cannot install haystack through pip (windows)

[Ebi117]

Describe the bug
When I run "pip install farm-haystack" I receive an error relating to torch.

Error message
The error I encounter:
ERROR: Could not find a version that satisfies the requirement torch==1.5.* (from farm==0.4.6->farm-haystack) (from versions: 0.1.2, 0.1.2.post1, 0.1.2.post2)
ERROR: No matching distribution found for torch==1.5.* (from farm==0.4.6->farm-haystack)

Expected behavior
A clear and concise description of what you expected to happen.

Additional context
I managed to install the package before and I had to reset my anaconda, I also recently installed docker to be able to use the elasticsearch functionality.

To Reproduce
Steps to reproduce the behavior

System:

• OS: Windows 10
• GPU/CPU:
• Haystack version (commit or version number):
• DocumentStore:
• Reader:
• Retriever:

Hi @Ebi117, this issue is resolved on the latest haystack master branch but it is not yet released on the PyPI package repository. In the meantime, can you try installing haystack from source:

git clone https://github.com/deepset-ai/haystack.git
cd haystack
pip install --editable .

[Ebi117]

I tried this now and got the following error:
ERROR: Could not find a version that satisfies the requirement torch<=1.6.0,>=1.5.1 (from farm==0.4.7->farm-haystack==0.3.0) (from versions: 0.1.2, 0.1.2.post1, 0.1.2.post2)
ERROR: No matching distribution found for torch<=1.6.0,>=1.5.1 (from farm==0.4.7->farm-haystack==0.3.0)

Is there any other workaround? I have tried installing torch separately to no avail.

[Ebi117]

@tanaysoni I have tried installing torch separately from pytorch with the following command:
pip install torch==1.6.0+cpu torchvision==0.7.0+cpu -f https://download.pytorch.org/whl/torch_stable.html

After that, I tried installing haystack using the method you provided and get the same error message:
ERROR: Could not find a version that satisfies the requirement torch<=1.6.0,>=1.5.1 (from farm==0.4.7->farm-haystack==0.3.0) (from versions: 0.1.2, 0.1.2.post1, 0.1.2.post2)
ERROR: No matching distribution found for torch<=1.6.0,>=1.5.1 (from farm==0.4.7->farm-haystack==0.3.0)

Hi @Ebi117 ,

We could replicate your issue on a windows machine.
The issue comes from PyTorch rather than Haystack.
Pytorch has only few versions available on PyPi, but has additional wheels at a custom location.
Their recommended way to install pytorch via pip on windows: pip install torch -f https://download.pytorch.org/whl/torch_stable.html (see here)

Can you please try to install via:

pip install farm-haystack -f https://download.pytorch.org/whl/torch_stable.html

[Ebi117]

Hi @tholor

I tried the command as you recommended and it worked to some extent that most of the packages got installed. I did however receive a incompatible error with torchvision and bokeh packages. Here is the output from the command you specified, I've bolded the error lines:

Seems that you are installing in an environment that already had torchvision and bokeh installed?
For haystack that should be fine. If you run torchvision or bokeh somewhere else I would recommend to setup a different environment via conda or virtualenv to avoid version conflicts.
