In the case that
<pre><code>pip install -U numpy 
</code></pre>
doesn't work (even with sudo), you may want to make sure you're using the right version of numpy. I had the same &quot;numpy.core.multiarray failed to import&quot; issue, but it was because I had 1.6 installed for the version of Python I was using, even though I kept installing 1.8 and assumed it was installing in the right directory.
I found the bad numpy version by using the following command in my Mac terminal:
<pre><code>python -c &quot;import numpy;print(numpy.__version__);print(numpy.__file__)&quot;;
</code></pre>
This command gave me the version and location of numpy that I was using (turned out it was 1.6.2). I went to this location and manually replaced it with the numpy folder for 1.8, which resolved my &quot;numpy.core.multiarray failed to import&quot; issue. Hopefully someone finds this useful!
Note: For the command, use double underscore before and after 'version' and 'file'

I had the same error after installing python and opencv in my D: drive (C: runs on a SSD). The problem seemed to be that my execution path was inside the numpy folder. You can check if that's the issue with this code :

<pre><code>import numpy

In case it retrieves any error related to the execution path, execute your original code from elsewhere. That solved the could not load numpy.core.multiarray error for me

blocks|key|166392|text|在我的例子中，这个问题是因为我安装了两个python+(2.7和3.5)，而pip只在3.5的python目录中安装numpy，而不管我使用的是哪个pip版本。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|166393|我通过显式指定目标安装目录解决了这个问题：|166394|pip+install+--target+c:\apps\python-2.7\Lib\site-packages+numpy|code-block|syntax|javascript|166395|entityMap^0|0|0|0^^$0|@$1|2|3|4|5|6|7|K|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|L|8|@]|9|@]|A|$]]|$1|D|3|E|5|F|7|M|8|@]|9|@]|A|$G|H]]|$1|I|3|-4|5|6|7|N|8|@]|9|@]|A|$]]]|J|$]]

In my case this problem was because I'd two python installations (2.7 and 3.5) and pip was installing numpy in the 3.5 python directory only, irrespective of which pip version I used.

I solved the problem by explicitly specifying the target install directory as such:

After having a nightmare using the pip install -U numpy several months ago, I gave up. I went through installing CV2s and opencv without success.

I was using numpy ver 1.9.1 on python34 and the upgrade just kept stalling on on 1.9.

So I went to <a href="https://pypi.python.org/pypi/numpy" rel="nofollow noreferrer">https://pypi.python.org/pypi/numpy</a> and discovered the latest numpy version for my python3.4. 

I downloaded the .whl file and copied it into the folder containing my python installation, C:\Python34, in my case. 

I then ran pip intall on the file name and I can now import cv2 problem free.

Make sure you close down python before you start, obvious but essential

Encountered this when trying to import Pytorch. Solved it by uninstalling or removing numpy repeatedly until no version was left on my Ubuntu and installing the newest version. In my case pip encountered <code>Access is denied</code> permission errors all the time maybe because of conflict with conda.
Run <code>sudo pip uninstall numpy</code>. If it refuses to delete the package from a <code>&lt;location&gt;</code> (make sure to make it the location of that specific package, not all packages - this is irreversible), run <code>sudo rm -r &lt;location&gt;</code>. Repeat above until the first command doesn't do anything and <code>import numpy</code> can't find the package within Python shell.
Install numpy using pip.

I had the same error message, after trying some of the suggested solutions without success, I found that I needed to run:

Once there was nothing left to uninstall, it was a matter of

<pre><code>pip install numpy

Tilde folders

In the event <code>pip uninstall numpy</code> and reinstallation of Numpy does not work. Review your site-packages folder for sub-folders beginning with a tilde ~ 

These folders relate to pip installations that got mangled and the installation was aborted part way through. The tilde folders were only ever meant to be tmp folders but ended up becoming permanent. In my case there was a file called ~mpy which was a mangled legacy Numpy folder. This led to compatibility issues and ImportErrors. 

These mangled folders can safely be deleted, for further details see <a href="https://stackoverflow.com/a/57488427/10341270">this answer</a>

I was able to solve the problem by updating my python to 3.8. I am using Macbook Air with Catalina. The problem started for me after updating TensorFlow. After updating it, the error doesn't disappear after I uninstalled and installed numpy several times.

I got this same error in a conda environment, only six+ years later. The other responses were helpful, and eventually I tracked it down to this problem:

<pre><code>&gt; conda list numpy
# packages in environment at [Anaconda3]:
#
# Name Version Build Channel
numpy 1.14.5 pypi_0 pypi
numpy-base 1.18.1 py36hc3f5095_1
numpydoc 0.9.1 pypi_0 pypi
</code></pre>

The problem was that 'numpy' was a different version than 'numpy-base'. I solved this with:

<pre><code>&gt; conda install numpy-base=1.14.5
</code></pre>

so the two of them matched each other.

In short, the version of NumPY that you need is v1.19.3:
<pre><code>pip uninstall numpy

pip install numpy==1.19.3

Or to do this in one command, use the --force-reinstall flag for pip:

~/home/anaconda3/envs//lib/python/site-packages/numpy
~/home/anaconda3/envs//lib/python/site-packages/numpy.libs
~/home/anaconda3/envs//lib/python/site-packages/numpy-.dist-info

<li>Install new Numpy with:
pip install numpy -U

ImportError: numpy.core.multiarray failed to import
</code></pre>
The important clue is <code>RuntimeError: module compiled against API version 0xe but this version of numpy is 0xd</code>.
Searching on that can get you to <a href="https://github.com/pypa/pip/issues/9542" rel="nofollow noreferrer">pip issue 9542</a> and <a href="https://github.com/cvxgrp/cvxpy/issues/1229" rel="nofollow noreferrer">cvxpy issue 1229</a> which explain what went wrong.
The workarounds in this case are to (a) update to <code>cvxpy&gt;=1.1.10</code>, or (b) update to <code>numpy&gt;=1.20</code>, or (c) update both. You'll have to cope with library changes since the original environment is not reproducible without diving into pip's <code>--no-build-isolation</code> world.

In case you uninstalled and reinstalled or installed update but it still not work, especially if you're packaging with cx_freeze:
<ul>
<li>Try to change your code by import numpy before import cv2.</li>
</ul>

I'm trying to run this program
<pre><code>import cv2
import time

cv.NamedWindow(&quot;camera&quot;, 1)

capture = cv.CaptureFromCAM(0)

while True:
 img = cv.QueryFrame(capture)
 cv.ShowImage(&quot;camera&quot;, img)
 if cv.WaitKey(10) == 27:
 break
cv.DestroyAllWindows()
</code></pre>
But I'm having a problem with numpy, I'm using pyschopy along with opencv.
The problem I keep getting is this error report:
<blockquote>
RuntimeError: module compiled against API version 7 but this version of numpy is 6
Traceback (most recent call last):
File &quot;C:\Users\John\Documents\EyeTracking\Programs\GetImage.py&quot;, line 1, in

<pre><code>import cv2
</code></pre>
ImportError: numpy.core.multiarray failed to import
</blockquote>
I have numpy-1.6.1-py2.7 in the psychopy folder, I'm just confused as to what is wrong?
Edit (Deleted Answer)
The following command
<pre><code>pip install -U numpy 
</code></pre>
helps solving the problem: <code>could not load numpy.core.multiarray.</code>

ImportError: numpy.core.multiarray failed to import
