ImportError: cannot import name 'indexable'

I don't use Jupyter, so when I copied the whole code (except the lines that are destined to work with Jupyter) to a python file and I run it in an environment where all the needed packages are installed (cv2, keras, matplotlib, numpy, pandas, sklearn, tensorflow), I got this error:

Using TensorFlow backend.

ImportError: cannot import name 'indexable'

I googled that, but I didn't find any solution.
Is it something related to the sklearn library or to the code?

I figured out that it was an error related to a filename, I renamed it and it is working fine.
