Hi! Thanks for sharing. Are you using MacOS?

from topologylayer.

I am also encountering the same error with the following specifications:
numpy==1.16.4 scipy==1.2.1 torch==1.1.0
python3.6.8
centos 4.18.0-193.28.1.el8_2.x86_64
gcc-c++-8.3.1-5.el8.0.2.x86_64
I built from source using python setup.py install --record files.txt
Could you please help?

I also had the error reported by @changshuowang on Ubuntu 21.10. Here are two setups that show the error and one that works. After installing the requirements with conda, I installed topologylayer with pip.

Error setup (1), requirements.yml:
channels:

• pytorch
• defaults
• conda-forge

dependencies:

• cudatoolkit=11.3.1
• matplotlib=3.4.3
• numpy=1.21.2
• python=3.9.7
• pytorch=1.9.0
• scipy=1.7.1

resulting in the following package versions:
