Keras installed but not working - windows

Question

I am using keras with theano as the back end to build a neural network on windows 10. My python version is 2.7. The problem is that when I try and use keras I keep getting a path error.
$python
>>import keras
Gives me the error
Problem occurred during compilation with the command line below:
"g++" -shared -g -DNPY_NO_DEPRECATED_API=NPY_1_7_API_VERSION -m64 -DMS_WIN64 -I"C:\Python27\lib\site-packages\numpy\core\include" -I"C:\Python27\include" -I"C:\Python27\lib\site-packages\theano-0.9.0-py2.7.egg\theano\gof" -L"C:\Python27\libs" -L"C:\Python27" -o C:\Users\Patrick\AppData\Local\Theano\compiledir_Windows-10-10.0.14393-Intel64_Family_6_Model_61_Stepping_4_GenuineIntel-2.7.11-64\lazylinker_ext\lazylinker_ext.pyd C:\Users\Patrick\AppData\Local\Theano\compiledir_Windows-10-10.0.14393-Intel64_Family_6_Model_61_Stepping_4_GenuineIntel-2.7.11-64\lazylinker_ext\mod.cpp -lpython27
The system cannot find the path specified.

I can tell that I need to add to my system variables paths (at least I think so...) but no matter what I add I still get the error. I have tried adding
C:\Python27\lib
C:\Python27\lib\site-packages
Basically any of the paths it said could not be specified. Something to note would be that I had a lot of trouble getting scipy installed and had to get the .whl file from http://www.lfd.uci.edu/~gohlke/pythonlibs/#scipy not sure if that helps at all. Well that's my issue.

Answer 1

I was also facing the same issue and resolved with removing other python versions. Make sure that you have only 1 python installed. If there is multiple, thing sometimes don't work very well.

Answer 2

What i would suggest is use keras in a separate environment using conda.
Suppose you want to create an env named "myenv"
1.Open Anaconda promt and type the following:
conda create --name myenv
2.To activate the environment:
conda activate myenv
3.Now you can install keras and other dependencies:
pip install keras
Install tensorflow as follows.
pip install tensorflow==2.0.0
