No module named 'scipy.sparse._sparsetools'

Question

I'm dealing with the following error with importing keras library:

>>> import keras

I've also checked these posts (QA-1, QA-2), but the problem still remains.

[NOTE]:

Python version: 3.6.9 Numpy version: 1.17.1 Keras version: 2.3.0
Scipy version: 0.17.0
OS: Ubuntu 16.04

• Guys, I don't want to use conda instead of pip

Answer 1

SciPy requires the following software installed for your platform:

Python >= 3.5 NumPy >= 1.13.3

update the libraries for 3.6

https://github.com/scipy/scipy/blob/master/INSTALL.rst.txt#linux

OR ELSE

According to from ._sparsetools import csr_tocsc, csr_tobsr, csr_count_blocks, \ImportError: DLL load failed: The specified module could not be found

Update your C++ redistributable compiler.

OR ELSE

Reinstall scipy using:

pip uninstall scipy
pip install scipy
