Question: I am trying to use NumPy in Python. I have just installed Anaconda Python 3.7, and that all seemed to go smoothly. However, I cannot import numpy(using the line import numpy). When I do, I get the following error:  C:\Users\jsmith\anaconda3\lib\site-packages\numpy\__init__.py:140: UserWarning: mkl-service package failed to import, therefore Intel(R) MKL initialization ensuring its correct out-of-the box operation under condition when Gnu OpenMP had already been loaded by Python process is not assured.

Importing the numpy c-extensions failed. - Try uninstalling and reinstalling numpy. - If you have already done that, then: 1. Check that you expected to use Python3.7 from "C:\Users\jsmith\anaconda3\python.exe", and that you have no directories in your PATH or PYTHONPATH that can interfere with the Python and numpy version "1.18.1" 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 - If you're working with a numpy git repository, try `git clean -xdf` (removes all files not under version control) and rebuild numpy. 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: DLL load failed: The specified module could not be found.  I can see it in the Enviorments tab of Anaconda Navigator, and when I try to use it in Eclipse(Pydev) it shows up under forced builtins. I took a look at my PYTHONPATH, and both my enviorment in Eclipse and my base python directory (jsmith/anaconda3) are in it. I have tried importing other libraries I see under forced builtins,and those work fine, yet numpy seems to be the only one with issues. Calling pip install numpy tells me it is already installed with version 1.18.1. I looked at this stack overflow page, and ran the first command in the answer(conda create -n test numpy python=3.7 --no-default-packages) in anaconda prompt. This worked, and then I realized the test was specific to the question, and tried base instead, and got this error: CondaValueError: The target prefix is the base prefix. Aborting.  However calling conda activate base did nothing.

Answer: As mentioned in the comments by @cel uninstalling and reinstalling numpy using pip uninstall numpy and pip install numpy made it work.
