ImageMagick 和 Wand 在 Anaconda 上的安装问题

Question

I'm currently on day three of attempting to install ImageMagick and Wand on my laptop to run on either jupyter or spyder in Anaconda.

First I got the "Shared Libraries not found" error which after uninstalling and re-installing a collaboration of different ImageMagick & Wand versions I got to resolve it. Only to be faced with the "MagickGetImageFeatures not found" error.

This is the test code I'm trying to run in order to test the code: from wand.image import Image as img

Here are the specs of my device and relevant packages:

• Python 3.7.8 (tags/v3.7.8:4b47a5b6ba, Jun 28 2020, 10:03:53) [MSC v.1916 64 bit (AMD64)]
• 64- bit operating system
• Windows 10 Pro
• Anaconda version 1.7.2

I have tried installing Ghostscript v5.92, and have changed the environment variables for MAGICK_HOME and using a virtual environment.

Any ideas on how to install ImageMagick and wand?

Thanks in advance!

The process steps I used to install the relevant packages are as follows:

1. I downloaded ImageMagick-6.6.9-10-Q16-windows-x64-dll.exe and ran the installation application making sure the Install development headers and libraries for C and C++ was checked. I set the MAGICK_HOME environment variable to the path for the installed file (C:Program Files\Imagemagick-6.6.9.10-Q16)
2. I then ran pip install wand==0.5.7 in my device cmd prompt
3. I then ran pip install ghostscript in my device cmd prompt
4. I used conda list to confirm the installation of the three packages before opening jupyter notebook

Install the latest ImageMagick DLL version directly from imagemagick.org (guide for windows) , and point MAGICK_HOME at the installation location. But first ensure all other version are uninstalled/removed from the system. Same for the Wand package via pip.

The MagickGetImageFreatures method was added about 10 years ago to ImageMagick-7, and not included with ImageMagick-6. Wand is aware of ImageMagick-7 exclusive features, and should only attempt to load them if they are available.
