No matching distribution found for torch==1.5.0+cpu on Heroku
I am trying to deploy my Django app which uses a machine learning model. And the machine learning model requires pytorch to execute.
When i am trying to deploy it is giving me this error

ERROR: Could not find a version that satisfies the requirement torch==1.5.0+cpu (from -r /tmp/build_4518392d43f43bc52f067241a9661c92/requirements.txt (line 23)) (from versions: 0.1.2, 0.1.2.post1, 0.1.2.post2, 0.4.1, 0.4.1.post2, 1.0.0, 1.0.1, 1.0.1.post2, 1.1.0, 1.2.0, 1.3.0, 1.3.1, 1.4.0, 1.5.0)

My requirements.txt is 

asgiref==3.2.7

chardet==3.0.4
cycler==0.10.0
dj-database-url==0.5.0
Django==3.0.6

six==1.14.0
sqlparse==0.3.1
torch==1.5.0+cpu
torchvision==0.6.0+cpu
urllib3==1.25.9
whitenoise==5.0.1



And runtime.txt is python-3.7.5
However installing it on my computer is not giving any type of error when i use command pip install torch==1.5.0+cpu I am using python 3.7.5 and pip 20.0.2. 
Complete code is here.
How to solve this issue i really need to deploy my app. Thanks

PyTorch does not distribute the CPU only versions over PyPI. They are only available through their custom registry.

If you select the CPU only version on PyTorch - Get Started Locally you get the following instructions:

pip install torch==1.5.0+cpu torchvision==0.6.0+cpu -f https://download.pytorch.org/whl/torch_stable.html


Since you're not manually executing the pip install, you cannot simply add the -f https://download.pytorch.org/whl/torch_stable.html.

As an alternative, you can put it into your requirements.txt as a standalone line. It shouldn't really matter where exactly you put it, but it is commonly put at the very top.

-f https://download.pytorch.org/whl/torch_stable.html
