Hi Jeff,
Hmmm, Could you try doing the same thing on just an in-memory numpy array
using numexpr
anthony,
where am I going wrong here?
#!/usr/local/bin/python3
import tables
import numpy as np
import datetime, time
encoding = 'UTF-8'
test_file = 'test_select.h5'
handle = tables.openFile(test_file, w)
node = handle.createGroup(handle.root, 'test')
table = handle.createTable(node, 'table',
Hi Jeff,
Have you also updated numexpr to the most recent version? The error is
coming from numexpr not compiling the expression correctly. Also, you might
try making selector a str, rather than bytes:
selector = (column == 'str-2')
rather than
selector = (column == 'str-2').encode(encoding)
for PyTables

Hi Jeff,
Hmmm, Could you try doing the same thing on just an in-memory numpy array using
numexpr. If this succeeds it tells us that the problem is in PyTables, not
numexpr.
Be Well
