OSError: [Errno 12] Cannot allocate memory with ccs.Summaries()

[khdcrawford]

I'm now getting a 'Cannot allocate memory' error when creating Summaries objects, even for my small test dataset in the alignparse/notebooks directory.

I'm not familiar enough with how the pathos multiprocessing works to really know how to debug this.

I think this is actually a server issue rather than alignparse issue. When running on the home rhino node, it often won't allow you to get any CPUs and will throw a memory error when you try.

Just try running with ncpus=1 if you are doing this on the home rhino node and it will probably work fine.

Or use grabnode to grab a node so you aren't running on home rhino.

Does this fix it?

Yeah, was coming to the conclusion that the error was on my end. ncpus=1 fixed it. Thanks!
