Review comment:
Just checked multiple versions of this, it will return -1 with the last
error message being:
`Check failed: header == kMXAPINDArrayListMagic Invalid NDArray file format`
Python can check for that pretty easily.
Just added a check against NULL pointers which I didn't think of originally.
