error of import scipy.stats for windows 7 - python-3.x

I use windows 7 and installed python 3.5 32bit. I installed numpy 1.11 + mkl win32 whl version for python 3.5 from http://www.lfd.uci.edu/~gohlke/pythonlibs/
and installed scipy 0.17.0 from the same site same way. I use pip install. No problem import numpy and scipy, but see error when import scipy.stats or from scipy import stats, etc... Here is the error message:
if from scipy import stats:

I have searched for solution from websites but could not find an answer. Please help. This is really frustrating...
Thanks

Ok, finally I solved this myself. At the beginning I knew I needed the 2015 visual C++ redistribution and had it installed, the problem is I installed the 64bit one while obviously I should have used 32 bit one since my python and numpy, scipy were all 32 bit.
Hope this helps for other people

Why does a DLL error appear when importing tensorflow?

I recently got a new 64-bit windows 10 and installed pycharm. The pycharm I am using is Python 3.8.
When I installed tensorflow by running the command line, it worked fine. However, when I imported on my pycharm file (i.e. import tensorflow as tf), it produced an error as such:
Traceback (most recent call last):
File "C:\Users\leode\anaconda3\envs\Science Fair\lib\site-packages\tensorflow\python\pywrap_tensorflow.py", line 64, in <module>
from tensorflow.python._pywrap_tensorflow_internal import *
ImportError: DLL load failed while importing _pywrap_tensorflow_internal: The specified module could not be found.
During handling of the above exception, another exception occurred:

Failed to load the native TensorFlow runtime.
However when I import tensorboard_plugin_wit:
import tensorboard_plugin_wit
It works fine.
What went wrong? If any of you need any further clarification, please comment- I'm not much of an expert on handling computers so I will do my best to answer:)
I figured out what the problem was. Unlike many third-party modules in python, installing tensorflow requires more than simply pip install . The way I installed tensorflow was by creating and activating a conda environment. For more information on how to install tensorflow via Pycharm, here is a helpful Youtube video: https://www.youtube.com/watch?v=5Ym-dOS9ssA&t=327s

The error is due to a glitch happening during the update due to pip. Related SO post is https://stackoverflow.com/a/59355676/6513708
But long story short, you need to remove the following files which were let by pip during the update:

ImportError: Importing the multiarray numpy extension module failed

I am trying to write Python script in Java using ScriptEngine. But when I import tflearn module it gives me following errors.
javax.script.ScriptException: ImportError:
Importing the multiarray numpy extension module failed. Most
likely you are trying to import a failed build of numpy.
If you're working with a numpy git repo, try `git clean -xdf` (removes all
files not under version control). Otherwise reinstall numpy.

Numpy is written in Fortran and compiled to binary. For that reason, it is not compatible to be ran on the JVM. The other packages you are importing are implemented in pure python.
CPython, the standard python implementation, has done a lot of work to stay compatible at the binary level. Numpy arrays have the same memory layout as C arrays, which do not have the same memory layout as Java arrays. As you go deeper into python there are a lot more incompatibilities as to why it won't work.

scipy.stats attribute not found

I tried to import scipy.stats as ss but it keeps showing me an import error:
Traceback (most recent call last):
File "E:\My Python Files\KNN_Classification.py", line 4, in <module>
import scipy.stats
File "D:\Python3.6\lib\site-packages\scipy\stats\__init__.py", line 343, in <module>

What should I do?
Most likely a wrong installation. You should remove the build directory as well as the installed scipy in site-packages, and then reinstall scipy.

Python cannot import name 'NUMPY_MKL'

I am trying to run a wavenet implementation (which uses tensorflow + librosa). However, I keep running into the error "cannot import name 'NUMPY_MKL'".
I have already installed tensorflow, numpy+mk1, scipy and librosa. Tensorflow itself is loading fine, but error is triggered when I run the wavenet implementation which uses librosa.
My spec/details:
Python 3.5.2
Numpy+MK1 (numpy-1.13.1+mkl-cp35-cp35m-win_amd64.whl)
Scipy (scipy-0.19.1-cp35-cp35m-win_amd64.whl)
Windows 10 x64
Nvidia CUDA v8.0 (cudnn 5.1)
Hope you can help. Full error log below:

Managed to fixed this by doing a complete uninstall of numpy+mk1, then installing it again.
I was previously doing:
pip install --ignore-install path\numpy.whl
Do this instead to get it working:
pip uninstall numpy # this removes the existing copy
pip install path\numpy.whl # this install the numpy+mk1 from local .whl file
