Hello, I would like to ask you a question about the installation of compressai “Successfully installed compressai-1.2.4.dev0” . I successfully installed cmpressai, but I got the following error when importing:

import compressai
Traceback (most recent call last):
File "", line 1, in
File "F:\compressai\compressai_init_.py", line 30, in
from compressai import (

from compressai.ans import BufferedRansEncoder, RansDecoder
ImportError: DLL load failed while importing ans: 找不到指定的程序。

Hi, this could be due to the merge of the PR on GMM using cpp torch extensions. This needed to be handled with care as the build needs to match cuda / python used to build torch. I reverted to a classical use of pybind of the ANS cpp extension as we provide compressai as a package and it's complicated to support all versions. Please pull the current master or tag 1.2.5 and re-install. Let me know if the problem persist and please provide your environment as detailed in the template issue.
