make_video_helper() missing 3 required positional arguments: 'x', 'in_dir', and 'tmp_ext'

When I run the code, and I got something wrong, how to solve(Ubuntu, tensorflow-gpu1.8)
multiprocessing.pool.RemoteTraceback:

The above exception was the direct cause of the following exception:

It can be solved by adding subscript, e.g. xs[0],xs[1]...
