I was creating a new env in anaconda and after installing spyder, tensorflow and theano I attempted to install keras but I got an error message (see below). Now I cannot even open spyder as it stops working. Spyder only works if I uninstall keras again.

Do you have any idea what could be going on? I have another env in this same computer that works perfectly with the same packages installed.

(py36) C:\Users\LeicaMicroscope>conda install -c conda-forge keras
Solving environment: done

It may sound really obvious, but did you try installing it with pip ?

  • I wasn't able to fix that environment. I created another one and installed with pip from the very first time and that worked. For some reason, installing keras via conda was breaking spyder. Thank you! – Carlos Galicia Jun 17 '18 at 23:41

I've resolved this by uncommenting everything inside the keras_activate.bat and keras_deactivate.bat file of my conda environment. You can locate this under %HOME%\Anaconda3\envs\<env_name>\conda. Btw, I have my keras working with tensorflow backend by default.

I've tried

conda install -c anaconda keras-gpu

for installing keras and it worked.
