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.
Original error was: cannot import name multiarray

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.

I composed a docker image file that gets built successfully.
However, when I run a container with that image, it produces the following numpy error and exits.
Any idea how this could be corrected?

IMPORTANT: PLEASE READ THIS FOR ADVICE ON HOW TO SOLVE THIS ISSUE!
Importing the numpy C-extensions failed. This error can happen for
many reasons, often due to issues with your setup or how NumPy was
installed.
We have compiled some common reasons and troubleshooting tips at:
https://numpy.org/devdocs/user/troubleshooting-importerror.html
Please note and check the following:
* The Python version is: Python3.9 from "/opt/venv/bin/python"
* The NumPy version is: "1.21.2"
and make sure that they are the versions you expect.
Please carefully study the documentation linked above for further help.

Did you install numpy outside of docker, and copied the venv?
If so, C extensions were compiled for your host (which, according to the error, is not Linux)
You'll need to install numpy into the container itself
I used Pycharm 2019.1's import optimization on a full project and now the imports for matplotlib and numpy don't work.

RuntimeError: implement_array_function method already has a docstring
I'm new here and honestly don't know what this ( RuntimeError: implement_array_function method already has a docstring) means.
Any help is much appreciated.
I had the same issue and the solution for me appeared when I realized that I had imported torch as two different names in different files in the same project. By renaming them I got rid of the error. I suspect you might have a similar issue. Try running the code in a new project without any other files in the same project.
I tried to import scipy.stats as ss but it keeps showing me an import error:
Traceback (most recent call last):

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.
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
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/

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
