h5py cant open file: BlockingIOError: [E 11] Unable to open file (unable to lock file, errno = 11, error message = 'Resource temporarily unavailable')

Question

I'm trying to open a h5 file using:

f = h5py.File('galpro/model1/posteriors/posteriors.h5', 'r')

And I get the error

BlockingIOError: [Errno 11] Unable to open file (unable to lock file, errno = 11, error message = 'Resource temporarily unavailable')

I originally got the error:

OSError: Unable to open file (bad object header version number)

However, once I redownloaded the file it gave me the 'BlockingIOError: [Errno 11] Unable to open file (unable to lock file, errno = 11, error message = 'Resource temporarily unavailable')' error message.

I'm not sure what's wrong or how to open the file. Please help!

Nb: I found that upgrading iPython and h5py packages solved the problem
