AttributeError: 'module' object has no att

问题:

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.

回答1:

Update dask to 0.15.0 will solve the issue

update cmd: conda update dask

input pip show dask will show follow message

Name: dask
Version: 0.15.0
Summary: Parallel PyData with Task Scheduling

回答2:

dask-0.14.3 works and eliminates the import error

回答3:

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

回答4:

The full command I use is

conda install pandas=0.19.2

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

回答5:

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!
