import pandas - ModuleNotFoundError: No module named 'numpy.testing.decorators'

I'm having troubles importing pandas:
import pandas

In [7]: import pandas
Traceback (most recent call last):

I recently fully reinstalled anaconda with home-brew; moreover, I installed the following:
pip install numpy==1.18
pip install scipy==1.1.0
pip install scikit-learn==0.21.3
pip install pandas
The pandas version I'm using is 0.25.1
Does anyone have an idea of what might be going wrong?

Upgrade to pandas 1.0.0 (If you have no other reason not to) via,
pip install -U pandas
See if it helps.

pip uninstall numpy
pip install numpy==1.17.0

macOS python3 with brew, error on import cv2

I installed python3 in my macOS through brew, I installed opencv and numpy, when I import cv2 and numpy I have this error
ModuleNotFoundError: No module named 'numpy.core._multiarray_umath'
Traceback (most recent call last):
File "001.py", line 2, in <module>
import cv2
File "/usr/local/lib/python3.7/site-packages/cv2/__init__.py", line 89, in <module>
bootstrap()
File "/usr/local/lib/python3.7/site-packages/cv2/__init__.py", line 79, in bootstrap
import cv2
ImportError: numpy.core.multiarray failed to import

I fix the problem in this way:
I installed opencv using brew
brew install opencv
I installed opencv for python
pip install opencv-python
I removed (bad) numpy library
sudo rm -rf /usr/local/lib/python3.7/site-packages/numpy
I linked numpy library with working library
sudo ln -s /usr/local/Cellar/numpy/1.17.1/lib/python3.7/site-packages/numpy /usr/local/lib/python3.7/site-packages/numpy

Why python3.5 links python2.7's numpy?

Update the problem:
I use
sudo python3
>>import numpy
It works!
And I use the suggestion of below comments :
delete the /usr/local/lib/python2.7/site-packages in path.
and the problem solved!
======== the old problem ===========
I'm using Mac OS El Capitan.
The Python2.7 is the default version; python3.5 is installed from the official site python3.5 for mac.
I have already installed numpy in python2.7. Now I need to install numpy in python3.5.
I use:
pip3 install numpy
which return
"Requirement already satisfied (use --upgrade to upgrade):
numpy in /usr/local/lib/python2.7/site-packages"
and when I run
python3
>>import numpy
in python3
it outputs:

It link the 2.7 package.. and show error.
(Similar Problem happens when I install scipy and sklearn)
How to solve the problem?

I ran into the same problem. Uninstalling numpy using pip3, and reinstalling, fixed the issue.
pip3 uninstall numpy
pip3 install numpy

An easy way to avoid this is to install all these modules using anaconda.

It will avoid you the headache of installing manually.

numpy.core.multiarray failed to import

I used the following command to know the numpy version I am using
pip show numpy
output shown below
---
Name: numpy
Version: 1.8.2
Location: /usr/lib/python2.7/dist-packages
Requires:
However when I am running matplotlib, I got a error as

I tried to upgrade numpy,
pip install numpy --upgrade
it shows to be installed successfully, but numpy still shows to be 1.8.2 and error continues to exist when running matplotlib.
I thought to uninstall numpy and reinstall it, the system gives the message saying
Not uninstalling numpy at /usr/lib/python2.7/dist-packages, owned by OS
how to solve it ?
any idea about
RuntimeError: module compiled against API version a but this version
of numpy is 9

How can I upgrade numpy? might be working for you. IN that case it was a path problem:
RuntimeError: module compiled against API version 9 but this version of numpy is 6
Traceback (most recent call last):
File "<string>", line 1, in <module>
ImportError: numpy.core.multiarray failed to import
Solution:
Check the path
import numpy
print numpy.__path__
and manually delete it using rm

I also had the same problem until I came across this Issue on Pytorch github repository. This command worked perfectly for me:
pip install numpy -I
It is also mentioned there that pip install numpy --upgrade is not working(don't know why). You can check the above mentioned link.

I had a similar problem with numpy when running torch. I tried uninstalling numpy and installing it using -U but it didn't work. After some search, I found this link and it solved my problem. It says you should change your numpy version.
pip uninstall numpy
pip install numpy==1.19.3

The answer is probably simple.
Just add
import numpy.core.multiarray
before the
import cv2
statement.
It worked fine for me.

My problem is solved using the old version of numpy. The solution is to use numpy 1.19.3.
pip install numpy==1.19.3

Installing the previous version of NumPy, 1.19.3 should fix this.
python -m pip install numpy==1.19.3

scikits.audiolab doen't import into python (numpy.dtype)

I have installed (with lots of troubles) scikits.audiolab for making sounds out of data. Now when I type:
import scikits.audiolab I get the following error
>>> import scikits.audiolab
Traceback (most recent call last):

ValueError: numpy.dtype does not appear to be the correct type object
How do I fix this?
Any alternative package that can do the job?

I had the same issue and for me it was caused by installing another (more recent) version of NumPy.
Check if you have different versions of NumPy installed and try switching back to an older one. For my part: I had a system-wide installation of Python and common modules like NumPy, which I couldn't touch because I'm not admin on that system. So when I installed some other library locally (in ~/.local/lib/python2.7/) it would also install more recent versions of SciPy and NumPy and put them into that local folder. And when importing the module it would draw from the local directory first before looking at the system-wide libraries which were working fine before with scikits.audiolab. So for me it was solved by
pip uninstall numy && pip uninstall scipy because that only deleted the newer local versions of numpy.
But more specific to your case, here is a tutorial how (on a Mac) to switch to a certain version of NumPy:
multiple numpy version on Mac OS X
The NumPy version I found working for my scikits.audiolab is 1.6.1
>>> import numpy
>>> numpy.version.version
'1.6.1'
Hope that helps. :)

Maybe you installed/upgraded numpy after installing talkbox. Try running this command:
pip install --upgrade --force-reinstall scikits.talkbox
