requirements.txt not equal operator causing dependency and resolution errors
Following the pip documentation I suggest you use either one of these operators in your requirements.txt:
SomePackage # latest version
SomePackage==1.0.4 # specific version
SomePackage>=1.0.4 # minimum version
Error is the following:
ERROR: Could not find a version that satisfies the requirement scipy~=1.4.1 ERROR: No matching distribution found for scipy~=1.4.1
try to install the package manually
try to install the package manually
Totally defeats the purpose of pip.
u can use command prompt as administrator .
then type py -m pip install (package name)

try to install the package manually
Totally defeats the purpose of pip. all package have already been listed in requirement.txt
