This is a very similar problem to as described in this issue, and the linked issue
It seems that only canopy
is experiencing these issues. I think it has to do with the canopy numpy MKL build, but that is a guess as I have not been able to reproduce this. So here are some work-arounds:
- try to upgrade
numexpr
to 2.4 (current version), or downgrade to2.1
- try to use
numpy 1.8.1
via canopy - try to install numpy/numexpr from the posted binaries here; I don't know exactly how canopy works so not sure if this is possible
- uninstall
numexpr
you can also disable numexpr
support via pandas.computation.expressions.set_use_numexpr(False)
. Note that numexpr
is REQUIRED in order to read/use HDF5 files via PyTables
. However the expressions disabling of numexpr
should just disable it for 'computations' (and not the HDF access).
