Im trying to use Keras (Sequential) but I get the following error when I try to import it:

Im running Python 2.7, TensorFlow 1.1 , Keras 2.0.3 and 'upgraded' to Pandas 0.20.1 yesterday which I suspect is causing the problem but the error message says nothing about it.

how did you update pandas ? are you sure that your python from anaconda can access it ? — Dadep

I did used conda and pip. I just used .__version__ to check the pandas version it was accessing and it came back with 0.20.1 — Greg

This is due to the new release of pandas (0.20.1). A new release of dask came out on Friday to fix things that broke in the new pandas release. Updating dask to 0.14.3 should fix your error. — jiminy_crist

Updating dask worked for me. However I updated it through pip rather than conda: pip install --upgrade dask

dask-0.14.3 works and eliminates the import error

I reverted back to Pandas 0.19.2 and it resolved this problem.

I think the better answer is to update dask as shown here: stackoverflow.com/a/44615129/1863542

The full command I use is

conda install pandas=0.19.2

and answer y to downgrade the pandas and it worked now.

I had installed below versions:

python 3.5
tensorflow 1.2.1
pandas 0.21
dask 0.15.3

and was getting the following error:

pd.core.computation.expressions.set_use_numexpr(False)
AttributeError: 'module' object has no attribute 'expressions'

I downgraded to pandas 0.19.2 and dask 0.15.0 and the python script worked fine!
