[Group conv support] ValueError: number of input channels does not match corresponding dimension of filter, 96 != 48

Hi,

I converted BVLC_AlexNet from Caffe to IR first. Then converted IR to Tensorflow code snippet in order to use it to get the checkpoint file. But when I tried to test my converted model by executing python -m mmdnn.conversion.examples.tensorflow.imagenet_test -s tensorflow -p AlexNet -n BVLC_AlexNet -w BVLC_AlexNet.npy, the error happened below:

If you wanna take a look at my converted model, here is the link
Can you please deal with it?
Thanks.

Hi @seanchung2 . Same problem with xception. Not support Conv with groups now. Will implement it soon. Thanks.

@seanchung2 master branch enables the groups convolution. Please try it. Thanks.

Hi @seanchung2 ,
caffe alexnet -> tf tested.

master branch with following scripts:

$ python -m mmdnn.conversion._script.convertToIR -f caffe -d kit_imagenet -n examples/caffe/models/bvlc_alexnet.prototxt -w examples/caffe/models/bvlc_alexnet.caffemodel

$ python -m mmdnn.conversion._script.IRToCode -f tensorflow --IRModelPath kit_imagenet.pb --dstModelPath kit_imagenet.py -w kit_imagenet.npy

$ python -m mmdnn.conversion.examples.tensorflow.imagenet_test -n kit_imagenet.py -w kit_imagenet.npy --dump ./caffe_alexnet.ckpt

Tensorflow file is saved as [./caffe_alexnet.ckpt], generated by [kit_imagenet.py] and [kit_imagenet.npy].
