I’ve tried build the Hail source locally, and followed the instructions given on the Getting Started page. I was able to build the source successfully, but when I tried to import Hail in a Python shell or Jupyter notebook, I get the following error.
.../hail/python/hail/typecheck/__init__.py", line 1, in <module> from check import * ModuleNotFoundError: No module named 'check'
Is this some error in the Hail modules, or am I missing something? Any help would be appreciated.
I’m using a laptop running OS X 10.12 with Python 2.7, Python 3.6, Anaconda 4.4.0 and Spark 2.0.2 installed.
EDIT: The issue is resolved now. The problem was that the Anaconda distribution I was using came with Python 3.6, and even though I had Python 2.7 installed, it wasn’t the version that was used when I ran it on Jupyter. The
types module in Python 3.x differs significantly from that in Python 2.7, which caused the
typecheck modules not to work.
