Windows Diffvg missing module

[ib0b]

Environment

Windows 10 , Python Version 3.7.4

Problem

After installation using python setup install I get this

Using c:\programdata\anaconda3\lib\site-packages
Finished processing dependencies for diffvg==0.0.1

But when running the example single circle i get this

(base) D:\GitHub\AI projects\diffvg\apps>python single_circle.py
Traceback (most recent call last):
  File "single_circle.py", line 1, in <module>
    import pydiffvg
  File "C:\ProgramData\Anaconda3\lib\site-packages\diffvg-0.0.1-py3.7-win-amd64.egg\pydiffvg\__init__.py", line 4, in <module>
    from .render_pytorch import *
  File "C:\ProgramData\Anaconda3\lib\site-packages\diffvg-0.0.1-py3.7-win-amd64.egg\pydiffvg\render_pytorch.py", line 2, in <module>
    import diffvg
ModuleNotFoundError: No module named 'diffvg'

Testing if diffvg is available:

(base) D:\GitHub\AI projects\diffvg\apps>python -c "import diffvg"
Traceback (most recent call last):
  File "<string>", line 1, in <module>
ModuleNotFoundError: No module named 'diffvg'

Also checking the package exists on the folder:

Could there be something wrong with compilation or something like that? Also is it possible to have a compiled version? I don't mind for which OS. hopefully for non CUDA.

I am using Python version: 3.8.5. I have the same issue of locating diffvg after what seem as successful compiling, the output of running setup.py is:

After testing with finite_difference_comp.py given example:

Traceback (most recent call last):

ModuleNotFoundError: No module named 'diffvg'

After rename diffvg-0.0.1-py3.8-win-amd64.egg to diffvg, I got the following output: AttributeError: module 'diffvg' has no attribute 'FilterType'

I'm experiencing the same issue using both VS 2017 and 2019 on a fresh environment after formatting my HDD, did anyone solve this? It's driving me nuts.

[yael-vinker]

any updates regarding this issue?

[marzia-riso]

I followed the install and setup instructions as reported in the repo and the compilation of the diffvg library seems to be fine. However, every python app script ends while importing the pydiffvg module, since diffvg module cannot be located. Any updated about this issue?

[surjikal]

What worked for me, for whatever reason, is renaming the site-packages/diffvg-0.0.1-py3.8-win-amd64.egg/diffvg file to diffvg.pyd

[marzia-riso]

@surjikal It worked for me too! Thank you!

for me it was confused if it had to use my python folder or my conda folder, once I got that right it worked smooth

@ljq142105 , I believe I have solved this. For my install, I changed these lines in CMakeLists.txt cmake_minimum_required(VERSION 3.12) ->cmake_minimum_required(VERSION 3.18) find_package(PythonLibs REQUIRED)->find_package(PythonLibs EXACT 3.7 REQUIRED)

The CMake version may not make a difference, but in my case, the issue was that the built module was trying to use the python library for a newer version, so requiring exactly 3.7 fixed it.

It didn't solve my problem. I am running from a conda env. Only python 3.7 is installed.

I reinstalled my pillow library. It works for me.
