turns out it is indeed because the chi_sim.training_text I was using was
too large.
I downloaded it from langdata_lstm repository rather than langdata
repository, which appears to be a problem. (Sometimes it's bad to be too
careful :) )The .training_text from langdata is only 199kb but is like 20MB
from langdata_lstm.
I found out this problem by check the tmp .tif file generated, which turns
out to be 60MB, way too large.
