If you try to use the TensorFlow pod in your iOS app and load the gan_mnist.pb file, you'll get an error:
Could not create TensorFlow Graph: Invalid argument: No OpKernel was registered to support Op 'RandomStandardNormal' with these attrs. Registered devices: [CPU], Registered kernels:
<no registered kernels>
[[Node: z_1/RandomStandardNormal = RandomStandardNormal[T=DT_INT32, _output_shapes=[[50,100]], dtype=DT_FLOAT, seed=0, seed2=0](z_1/shape)]]
Make sure your tensorflow/contrib/makefile/tf_op_files.txt file has tensorflow/core/kernels/random_op.cc, which implements the RandomStandardNormal operation, and the libtensorflow-core.a is built with tensorflow/contrib/makefile/build_all_ios.sh after the line is added to tf_op_files.txt.
Furthermore, if you try to load the pix2pix_transformed_memmapped.pb even in the custom TensorFlow...
