The error happens on that line and it's hard to debug.

ValueError: negative dimensions are not allowed
And we print out shape in "return variable(np.random.uniform(low=low, high=high, size=shape)", and find shape becomes (-3840,4096), which means there is a negative dimension in the dense layer. Everything before looks OK. Do you know what might cause the issue?
