"No space left" error with Hail installed using conda

[danking]

How do I increase the memory or RAM available to the JVM when I start Hail through Python?

I’m using Hail via IPython on my laptop, like this: import hail as hl ibd = hl.read_matrix_table("/path/to/my.mt").identity_by_descent() When I try to run this, I get a big error message that starts with this: FatalError: OutOfMemoryError: Java heap space or OutOfMemoryError: GC overhead limit exceed How do I increase the memory available to the Java process?
