Hi Pascal,
I tried to use theano.gpuarray.dnn.dnn_conv but it doesn't work: raise
ValueError("Could not infer context from inputs")
ValueError: Could not infer context from inputs
from theano.gpuarray.dnn import dnn_conv
out = dnn_conv(img= input,
kerns= self.W,
border_mode='valid',
subsample=(1, 1,1),
conv_mode='conv',
direction_hint=None,
workmem=None,
algo=None,
precision=None)
This is the output testing the small 3dconvnet:
