AttributeError: module 'nksr' has no attribute 'Reconstructor'

感谢您分享的代码。按照您的指南配置好环境后，在运行demo的时候碰到以下报错，该如何解决呢？

My torch version is 2.0.0 and CUDA version is 11.8

[jeremycp3]

I guess there was a problem with pip install nksr:

WARNING: Skipping page https://nksr.huangjh.tech/whl/torch-2.0.0+cu118.html because the GET request got Content-Type: Unknown. The only supported Content-Types are application/vnd.pypi.simple.v1+json, application/vnd.pypi.simple.v1+html, and text/html

But I don't find how to fix it, can you give me some advice?

Hey, thanks for sharing the question. I have never met this problem before in my previous tests. My guess is that my website is blocked by GFW somehow. Could you please try the alternative link via:

pip install -U pip
pip install -U nksr -f https://nksr.s3.ap-northeast-1.amazonaws.com/whl/torch-2.0.0%2Bcu118.html

Thanks for your reply! It works, but a new error comes out.

I fixed it. The checkpoint was not downloaded well. That's the reason.

Nice! Glad it helps!
