GPU version can't work with keras. #45

Closed clockzhong closed 6 years ago

Hi, Mr. Guo, I've found a problem when using the GPU version. The following is my steps: python capsulenet-multi-gpu.py --gpus 2

Using TensorFlow backend. Namespace(batch_size=300, debug=0, digit=5, epochs=50, gpus=2, lam_recon=0.392, lr=0.001, routings=3, save_dir='./result', shift_fraction=0.1, testing=False, weights=None)

Layer (type) Output Shape Param # Connected to

conv1 (Conv2D) (None, 20, 20, 256) 20992 input_1[0][0]

primarycap_conv2d (Conv2D) (None, 6, 6, 256) 5308672 conv1[0][0]

digitcaps (CapsuleLayer) (None, 10, 16) 1474560 primarycap_squash[0][0]

input_2 (InputLayer) (None, 10) 0

I've installed pydot and graphviz already, and my keras version is:

keras.version '2.1.2'

Thanks!

@clockzhong Just comment out these two lines:

from keras.utils.vis_utils import plot_model

plot_model(model, to_file=args.save_dir+'/model.png', show_shapes=True)

这只是一种绕开问题的方法，真正的问题的root cause在keras的plot_model(里面，对吧？

See #7 and #25 Some resources can be found in https://github.com/keras-team/keras I don't remember how I fixed this problem, but I believe you can find a solution by using Google or Baidu.
