I have a very similar question to this question, but still one step behind. I have only one version of Python 3 installed on my Windows 7 (sorry) 64-bit system.
I installed numpy following this link - as suggested in the question. The installation went fine but when I execute
import numpy
I got the following error:
Import error: No module named numpy
I know this is probably a super basic question, but I'm still learning.
Thanks
This question is related to
python
python-3.x
numpy
import
scipy
import numpy as np
ImportError: No module named numpy
I got this even though I knew numpy was installed and unsuccessfully tried all the advice above. The fix for me was to remove the as np and directly refer to modules . (python 3.4.8 on Centos) .
import numpy
DataTwo=numpy.stack((OutputListUnixTwo))...
I'm not sure exactly why I was getting the error, but pip3 uninstall numpy
then pip3 install numpy
resolved the issue for me.
Those who are using xonsh
, do xpip install numpy
.
I had numpy installed on the same environment both by pip and by conda, and simply removing and reinstalling either was not enough.
I had to reinstall both.
I don't know why it suddenly happened, but the solution was
pip uninstall numpy
conda uninstall numpy
uninstalling from conda also removed torch
and torchvision
.
then
conda install pytorch-cpu torchvision-cpu -c pytorch
and
pip install numpy
this resolved the issue for me.
You installed the Numpy Version for Python 2.6 - so you can only use it with Python 2.6. You have to install Numpy for Python 3.x, e.g. that one: http://sourceforge.net/projects/numpy/files/NumPy/1.6.1/numpy-1.6.1-win32-superpack-python3.2.exe/download
For an overview of the different versions, see here: http://sourceforge.net/projects/numpy/files/NumPy/1.6.1/
I also had this problem (Import Error: No module named numpy) but in my case it was a problem with my PATH variables in Mac OS X. I had made an earlier edit to my .bash_profile file that caused the paths for my Anaconda installation (and others) to not be added properly.
Just adding this comment to the list here in case other people like me come to this page with the same error message and have the same problem as I had.
I had this problem too after I installed Numpy. I solved it by just closing the Python interpreter and reopening. It may be something else to try if anyone else has this problem, perhaps it will save a few minutes!
You can try:
py -3 -m pip install anyPackageName
In your case use:
py -3 -m pip install numpy
Thanks
You should try to install numpy using one of those:
pip install numpy
pip2 install numpy
pip3 install numpy
For some reason in my case pip2 solved the problem
Installing Numpy on Windows
This might be: C:\Users\\AppData\Local\Programs\Python\PythonXX\Scripts or C:\Program Files (x86)\PythonXX\Scripts (where XX represents the Python version number), depending on where it was installed. It may be easier to find the folder using Windows explorer, and then paste or type the address from the Explorer address bar into the command prompt.
You should see something similar to the following text appear as the package is downloaded and installed.
Collecting numpy
Downloading numpy-1.13.3-2-cp27-none-win32.whl (6.7MB)

Installing collected packages: numpy
Successfully installed numpy-1.13.3
As stated in other answers, this error may refer to using the wrong python version. In my case, my environment is Windows 10 + Cygwin. In my Windows environment variables, the PATH points to C:\Python38 which is correct, but when I run my command like this:
./my_script.py
I got the ImportError: No module named numpy
because the version used in this case is Cygwin's own Python version even if PATH environment variable is correct.
All I needed was to run the script like this:
py my_script.py
And this way the problem was solved.
For those using python 2.7, should try:
apt-get install -y python-numpy
Instead of pip install numpy
If it was working before reinstalling python would solve the issue.
I just hit and resolved this issue using: How can I install a previous version of Python 3 in macOS using homebrew?
this is the problem of the numpy's version, please check out $CAFFE_ROOT/python/requirement.txt. Then exec: sudo apt-get install python-numpy>=x.x.x, this problem will be sloved.
pip3 may not refer to the python3 you use.
run python3 -m pip install numpy
instead.
You can simply use
pip install numpy
Or for python3, use
pip3 install numpy
Faced with same issue
ImportError: No module named numpy
So, in our case (we are use PIP and python 2.7) the solution was SPLIT pip install commands :
From
RUN pip install numpy scipy pandas sklearn
TO
RUN pip install numpy scipy
RUN pip install pandas sklearn
Solution found here : https://github.com/pandas-dev/pandas/issues/25193, it's related latest update of pandas to v0.24.0
solution for me - I installed numpy inside a virtual environment, but then running ipython was not inside virtual env:
(venv) ? which python
/Users/alon/code/google_photos_project/venv/bin/python
(venv) ? which ipython
/usr/bin/ipython
so I had to install ipython, and run ipython from the venv like this:
python -c 'import IPython; IPython.terminal.ipapp.launch_new_instance()'
For installing NumPy via Anaconda(use below commands):
I was trying to use NumPy
in Intellij
but was facing the same issue so, I figured out that NumPy also comes with pandas
. So, I installed pandas with IntelliJ tip
and later on was able to import NumPy. Might help someone someday!
I think there are something wrong with the installation of numpy. Here are my steps to solve this problem.
python setup.py install
I too faced the above problem with phyton 3 while setting up python for machine learning.
I followed the below steps :-
Install python-2.7.13.msi
• set PATH=C:\Python27
• set PATH=C:\Python27\Scripts
Go to http://www.lfd.uci.edu/~gohlke/pythonlibs/#scipy
Downloaded:- -- numpy-1.13.1+mkl-cp27-cp27m-win32.whl
--scipy-0.18.0-cp27-cp27m-win32.whl
Installing numpy: pip install numpy-1.13.1+mkl-cp27-cp27m-win32.whl
Installing scipy: pip install scipy-0.18.0-cp27-cp27m-win32.whl
You can test the correctness using below cmds:-
>>> import numpy
>>> import scipy
>>> import sklearn
>>> numpy.version.version
'1.13.1'
>>> scipy.version.version
'0.19.1'
>>>
After trying many suggestions from various sites and similar questions, what worked for me was to uninstall all Python stuff and reinstall Anaconda only (see https://stackoverflow.com/a/38330088/1083292)
The previous Python installation I had was not only redundant but only caused me trouble.
For me, on windows 10, I had unknowingly installed multiple python versions (One from PyCharm IDE and another from Windows store). I uninstalled the one from windows Store and just to be thorough, uninstalled numpy pip uninstall numpy
and then installed it again pip install numpy
. It worked in the terminal in PyCharm and also in command prompt.
