[Pytables-users] openFile seems to hang

[Daniel W. <dan...@gm...>]

The following just seems to hang indefinitely.

In [1]: import tables


In [2]: f = tables.openFile('tmp.h5', mode='a')

The tests hang as well.

In [3]: tables.test()

Performing only a light (yet comprehensive) subset of the test suite.
If you want a more complete test, try passing the --heavy flag to this
script
(or set the 'heavy' parameter in case you are using tables.test() call).
The whole suite will take more than 4 hours to complete on a relatively
modern CPU and around 512 MB of main memory.

Any ideas are greatly appreciated.

Thanks.
