CudaNdarrayType only supports dtype float32 for now about dcgan_code

[Newmu]

Have you made sure theano.config.floatX is set to float32? The debug msg is suggesting symbolic variable going into a conv or deconv op (likely a downstream from "Z" or "Y") has dtype float64. Check Z.dtype and Y.dtype

[genekogan]

yes! that solved that problem. however it led to a new issue (HostFromGPU not defined, see below).
thanks for the repo, results look really amazing. sorry, still getting the hang of theano...

>> gX = gen(Z, Y, *gen_params)

Usually only seen an error like that when you don't have cuda/cudnn properly installed/configured. Can you confirm cuda/cudnn is working on your end?

[genekogan]

yes, works perfectly now, thank you! i had cuda/cudnn installed, just didn't have it in the PATH.
