I want to zip some sources in order to use it easily from multiple locations. I have to install some external modules, let us say pyyaml and numpy.
First, I install these packages in a specific location:
python -m pip install --target=lib pyyaml numpy
And then I create the zipped library:
python -m zipapp library --output=my_library.pyd --compress
In another interpreter, after adding "my_library.pyd" to the sys.path, I can load the yaml module, but not the numpy one:
>>> import sys
>>> from pathlib import Path
>>> sys.path.append(str(Path().absolute() / 'my_library.pyd'))
>>> import yaml
>>> import numpy

IMPORTANT: PLEASE READ THIS FOR ADVICE ON HOW TO SOLVE THIS ISSUE!
Importing the multiarray numpy extension module failed. Most
likely you are trying to import a failed build of numpy.
Here is how to proceed:
- If you're working with a numpy git repository, try `git clean -xdf`
(removes all files not under version control) and rebuild numpy.
- If you are simply trying to use the numpy version that you have installed:
your installation is broken - please reinstall numpy.
- If you have already reinstalled and that did not fix the problem, then:
1. Check that you are using the Python you expect (you're using D:\Apps\python-3.7\python.exe),
and that you have no directories in your PATH or PYTHONPATH that can
interfere with the Python and numpy versions you're trying to use.
2. If (1) looks fine, you can open a new issue at
https://github.com/numpy/numpy/issues. Please include details on:
- how you installed Python
- how you installed numpy
- your operating system
- whether or not you have multiple versions of Python installed
- if you built from source, your compiler versions and ideally a build log
Note: this error has many possible causes, so please don't comment on
an existing issue about this - open a new one instead.
Original error was: No module named 'numpy.core._multiarray_umath'
In the zip archive, I do have a file named numpy\core\_multiarray_umath.cp37-win_amd64.pyd, but it obviously is a C compiled file.
Is there anything I can do to be able and import numpy when creating the zip archive?
I believe this is a problem with zipapp on import some .c compiled files. To solve this I used the install creator. It was what I want, create a .exe from python code.

I have successfully called the 'import numpy' command from the anaconda command prompt so it seems the issue is just with VS-Code?
I have also tried to reinstall numpy from the environment with the following command conda install numpy --force-reinstall but this has no effect?
Try launching VS Code from your activated conda environment. Errors like this typically come up if you managed to run code before your shell had a chance to do a conda environment activation.
There is one step more
Launch Anaconda 3 powershell
conda init cmd.exe #to allow cmd to run VScode
Lauch VScode by the hitting the command code.

On all the forums, installation steps given are in context of pip/anaconda. I don't find lot of reference with installation on Ubuntu via apt/apt-get. This looked like installation error, so i tried this as well, but no luck. Please help!

python3-numpy is already the newest version (1:1.17.4-5ubuntu3).
0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.
Could this be python version issue?
This was the code I was trying :
import sys
import numpy as np
import matplotlib
print("Python: ", sys.version)
print("Numpy: ", np.__version__)
print("Matplotlib: ", matplotlib.__version__)
Solution was to use the python3 as command instead of python3.7
Issue can be marked closed with this conclusion.
I am using qiskit (I am an absolute beginner with some experience with Java and know basic python) but when I tried to run an example code which uses numpy it gave me this error. I tried reinstalling it but it gave me the same error.
I have tried installing and reinstalling it but it didnt work

Try to upgrade the numpy:
pip install --upgrade numpy
or uninstall it and reinstall it again:
pip uninstall numpy
pip install numpy
I'm tired to import cv and numpy and get errors. I started importing cv and I got this error:
ImportError: numpy.core.multiarray failed to import
Traceback (most recent call last):

So I installed numpy on Ubuntu using:
apt-get install python-numpy
So when I import numpy I get:
Traceback (most recent call last):
File "", line 1, in <module>
File "numpy/init.py", line 127, in <module>
raise ImportError(msg)
ImportError: Error importing numpy: you should not try to import numpy from
its source directory; please exit the numpy source tree, and relaunch
your python intepreter from there.
I really need help. I'm using Python 2.7.3 on Ubuntu.
There is nothing wrong with installing common dependencies using your operating system's package manager, remember using pip means your synaptic updates won't update your Python libraries and pip won't leverage the dependencies already taken care of by aptitude. For python packages with C extensions like numpy and opencv its probably better to use apt-get.
In Ubuntu you can install both dependencies with
sudo apt-get install python-numpy python-opencv
The actual Python error you are getting indicates what is wrong, namely that you are executing from within the numpy source directory, or have a file named numpy.py in your current directory which is confusing things at import time. Try change into an empty directory, start Python import your libraries:
import numpy
import cv
Hope that helps.
It's better that use some package management tool such like pip to install numpy.
For example,
pip install numpy
I've spent the day trying to get the h5py module of python working, but without success. I've installed HDF5 shared libraries, followed the instructions I could find on the web to get it right. But it doesn't work, below is the error message I get when trying to import the module into python. I tried installing through MacPorts too but again it wouldnt work.
I'm using Python27 32 bits (had too for another module, and thus installed the i386 HDF5 library... if that's right?)
Any help very welcome !
Thank you !
