No module named '_SimpleITK'

[jingxiweng]

Hi All, I recently started working on image registration. I was trying to use SimpleElastix. However, I have tried on both Ubuntu and windows 10, but still I can't import it into python successfully. I also did what was on the tutorial (reinstall vc_redist), but it didn't work either. I have seen people previously posted almost same question, but still I can't figure out how I should solve it. Below is the error log. It is my first time to post an issue, sorry for any wrong format.

import SimpleITK Traceback (most recent call last):

During handling of the above exception, another exception occurred:

By the way, now I am using a Windows system with anaconda, and there is no python2 installed. Is this error due to the version conflict between python 2 and python 3?

Got the same issue: (Windows 10 + Visual studio 2019 + Anaconda3)

ImportError: DLL load failed while importing _SimpleITK: The specified module could not be found.

SimpleElastix used to work for me for the versions 1.5 year and 2 years ago for Linux.
