Github not include to this (from noiseFilter import gasuss_noise,sp_noise,horizontal_flip))

so i find

output = np.zeros(image.shape,np.uint8)

for i in range(image.shape[0]):
for j in range(image.shape[1]):

if rdn < prob:
output[i][j] = 0
elif rdn > thres:
output[i][j] = 255
else:
output[i][j] = image[i][j]
return output

When I run batch_x_np, batch_joints_np = sess.run(next_ele) in run_train.py，a mistake has occurred:tensorflow.python.framework.errors_impl.InvalidArgumentError: Input to reshape is a tensor with 0 values, but the requested shape has 10
