Solution to the error : Negative dimension size caused by subtracting 3 from 1 for 'conv2d_2/convolution'

[Tyler871203]

I found the solution to this problem :
When you initiate a convolution layer,
the order of parameters of the input size should be (rows, cols, channel)
but in your code gestureCNN.py, loadCNN, line 151 says that:
model.add(Conv2D(nb_filters, (nb_conv, nb_conv),
padding='valid',
input_shape=(img_channels, img_rows, img_cols)))

so you should add a new parameter called "data_format" and set it to 'channels_first' like this :

model.add(Conv2D(nb_filters, (nb_conv, nb_conv),
padding='valid',data_format='channels_first',
input_shape=(img_channels, img_rows, img_cols)))

May I know which Tensorflow version are you using ?
