H5py Oserror: Unable To Open File (file Signature Not Found)

I'm a bit confused about an error I'm receiving when using h5py. I'm trying to apply a python script to loop through sets of h5py files located in different directories. For exampl

Solution 1:

I don't really know what I'm talking about here so sorry in advance if this doesn't make sense or help or just isn't related.

It's an extremely annoying error that no one has attempted to answer in over a year so I thought the tiny bit of knowledge I have might help.

I had a similar problem whilst working on a cluster. It turned out that h5py uses something called flock() and that this can sometimes have a negative effect on the filesystem performance.

Because of this flock() is sometimes not allowed. If you are working on someone elses filesystem then ask admin if they will alow it and if not then I can't find a way around it (I have not tried to find other libraries that don't use flock()).

If it is your own filesystem then you should be able to allow flock() but I'm not sure how to do this. This may help you if it's NFS

I would certainly be interested to hear how you got on?
