Hi all,
I have a loop that goes over a list of filenames I've generated, loads parameter files for them, passes each pf object to a procedure which grabs data from the file, and then loops back over. After the first iteration, I get this crash:
Traceback (most recent call last):

h5py._stub.IOError: File exists (File accessability: Unable to open file)
It does not matter where in the list of files I start, so it's not due to a single bad file. It's like it doesn't detect the file it's trying to read somehow, so it tries to create it, but then it finds out it already exists, and then aborts. Very odd.
Best,
John ZuHone
