isc_parser python library not installing in mac tried using pip

while installing requirements of this github repo:-
https://github.com/sentient-bread/CL-Project2
I am shown this error:-
ERROR: Could not find a version that satisfies the requirement isc_parser (from versions: none)
ERROR: No matching distribution found for isc_parser
i tried installing it using:-
pip install isc_parser and pip3 install isc_parser

ERROR: No matching distribution found for torch===1.7.0+cu110

Hi I got an error while trying to install pytorch:
PS C:\windows\system32> pip install torch===1.7.0+cu110 torchvision===0.8.1+cu110 torchaudio===0.7.0 -f https://download.pytorch.org/whl/torch_stable.html
Looking in links: https://download.pytorch.org/whl/torch_stable.html
ERROR: Could not find a version that satisfies the requirement torch===1.7.0+cu110 (from versions: 0.1.2, 0.1.2.post1, 0.1.2.post2)
ERROR: No matching distribution found for torch===1.7.0+cu110
I have seen this question, and I am using python 3.8.6
PS C:\windows\system32> py --version
Python 3.8.6

The newest version of torch is 1.7.0, so
pip install torch
should be enough.

PyTorch installation fails Could not find a version that satisfies the requirement

I'm trying to install PyTorch with PyCharm Community Edition 2020.2.3 x64 and Python 3.9.0 on Windows 10 pro 64-bit OS PC machine
I've tried:
pip install torch==1.7.0+cpu torchvision==0.8.1+cpu torchaudio===0.7.0 -f https://download.pytorch.org/whl/torch_stable.html
and:
python -m pip install torch==1.7.0 -f https://download.pytorch.org/whl/torch_stable.html
Should I downgrade Python version, let's say to Python 3.8.6 or PyTorch version, to make it work, or am I doing something else incorrectly besides this, maybe missed something to install, for example I did not selected CUDA, but seems like it is different reason:
ERROR: Could not find a version that satisfies the requirement
torch==1.7.0+cpu (from versions: 0.1.2, 0.1.2.post1, 0.1.2.post2)
ERROR: No matching distribution found for torch==1.7.0+cpu
with pip3 install https://download.pytorch.org/whl/cpu//torch-1.7.0%2Bcpu-cp38-cp38-win_amd64.whl:
ERROR: torch-1.7.0+cpu-cp38-cp38-win_amd64.whl is not a supported
wheel on this platform.
and
pip install torch==1.4.0+cpu torchvision==0.5.0+cpu -f https://download.pytorch.org/whl/torch_stable.html -vvv
ERROR: Could not find a version that satisfies the requirement
torch==1.4.0+cpu (from versions: 0.1.2, 0.1.2.post1, 0.1.2.post2)
ERROR: No matching distribution found for torch==1.4.0+cpu
Any advice, guide or example would be helpful
Solution:
Installed successfully with Python 3.8.6

I tried with Python 3.8.0, Python 3.8.5, Python 3.8.6 and Python 3.9.0. It seems to work only with 3.8.6 version.

ERROR: Could not find a version that satisfies the requirement tensorflow==2.1.0 and No matching distribution found for tensorflow==2.1.0

I am trying to use 'pipenv' on Windows Subsystem for Linux (ubuntu 18.04)
When I run
$ pipenv sync
I am getting this error :
[pipenv.exceptions.InstallError]: ['ERROR: Could not find a version that satisfies the requirement
tensorflow==2.1.0 (from -r /tmp/pipenv-gy0uz1a7-requirements/pipenv-glre38t7-requirement.txt (line 1))
(from versions: 2.2.0rc1, 2.2.0rc2)', 'ERROR: No matching distribution found for tensorflow==2.1.0
(from -r /tmp/pipenv-gy0uz1a7-requirements/pipenv-glre38t7-requirement.txt (line 1))']
I followed some other instructions that say I have to install tensorflow, so I installed tensorflow
$ pip install --upgrade pip
$ pip install tensorflow==2.1.0
Even after installing tensorflow 2.1.0 I am still getting the same error when I run
$ pipenv sync
What should I do to fix this problem?

Check your python version, the python 3.8 doesn't support TensorFlow 2.1 version.

can't install pywin32 --strange error

i tried to install pywin32 in Pycharm and in cmd with "pip install pywin32" and i got that massage:
Could not find a version that satisfies the requirement pywin32 (from versions: )
No matching distribution found for pywin32
