How can I use cuda and cudnn along with Keras, tensorflow, and theano using spyder? Please explain to me or lead me to a correct source. I know how to install everything but once I get to import theano, keras, or tensorflow on apyder, an error pops up saying it can’t find it

How did you install spyder, tensorflow, Keras and theano? What is your operating system? Hard to help without any detail.

I have no problem running all of these together on Ubuntu 16.04.
