(mkl was installed as a dependency by another package.)

In VS Code for Windows 11, I created a .py script that runs:

import mkl

Why does its PowerShell terminal displays the error below?

Hi James,

Thanks for posting in Intel communities.

'In VS Code for Windows 11, I created a .py script that runs: Why does its PowerShell terminal displays the error below?'

import mkl

>>Could you please confirm if Intel python is installed on your system?

In some cases, using a different distribution of Python or a package that doesn't rely on MKL can cause the issue. You could try using Anaconda distribution, which includes the Intel MKL library by default. More details regarding the same were provided below.

You could use the conda package manager in installing Intel Python and all other dependent packages. You could use the below command for the same.

>> conda create -n test -c intel intelpython3_full -y

You could install intel mkl using conda package manager using the below command

>> conda install -c intel mkl

If you have the Intel MKL library installed on your system, could you please confirm that it is properly installed and configured? If necessary, you might need to reinstall MKL or update it to a compatible version.

We have created a test environment and we could see mkl being imported without any issues.

Attached is the screenshot for your reference.

Thanks @ShanmukhS_Intel, I created a new environment for intelpython3_full.
