[Pytables-users] pytables: could not find the HDF5 runtime
Hi, I'm trying to install pytables and its proving difficult (using MAC OS 10.6.4). I have installed in /usr/local/hdf5 and set the environment variable $HDF5_DIR to /usr/local/hdf5.

Try leaving the pytables source dir and then running then running IPython.

Re: [Pytables-users] Problems with flush(): RuntimeError: dictionary changed size during iteration
I'm continuing to fight this error. As a sanity check I rewrote my sample
app as a single thread only. With interleaved read/writes to multiple
tables I still get RuntimeError: dictionary changed size during iteration
in flush. I still think there is some underlying problem or something I
don't understand about pytables/hdf5. I'm far from an expert on either of
these so I appreciate any suggestions or even confirmation that I'm not
completely crazy? The following code should work, right?

Re: [Pytables-users] Problems with flush(): RuntimeError: dictionary changed size during iteration
I think I have found a viable work around.
Previously, I was flushing the whole HDF5 file:
self.h5.flush()
By replacing this with a flush on just the table of interest:
table = self.tables[random.randint(0, self.num_groups-1)][random.randint(0,
self.num_tables-1)]
table.flush()
The RuntimeError seems to be gone in all versions of my test program (both
single threaded and threaded with locks). Hope this helps someone else and
eventually maybe someone will figure out what is wrong with File.flush().

Re: [Pytables-users] pytables: could not find the HDF5 runtime
Hi Anthony, Thanks for your reply. I installed HDF5 also from source. The reason I'm building hdf5 and pytables myself is that they don't seem to be available through EPD any more (at least in the free version: http://www.enthought.com/products/epdlibraries.php) They used to both come bundled in EPD, but not anymore, which is a pain.

Re: [Pytables-users] pytables: could not find the HDF5 runtime
Hi Jennifer, Yeah, that is right, they are not in EPD Free. However, they are in Anaconda CE (http://continuum.io/downloads.html). Note the CE rather than the full version.
