Objective

Create docker environment

Detail problems and solutions

I encountered many problems including no module named cv2, and buss error.
I summarize all the trials and solutions here: https://qiita.com/Mas-sensyn/items/2ffbe218051280ea5f16

Test

I tested using my own 5 min video. And confirmed it worked perfectly as below;

I pulled your branch and followed the instructions exactly with
docker compose up -d --build, but the image no longer builds.

The failure happens at Dockerfile step 9/13, in the conda run -n mast3r-slam ... pip install ... && pip install -e thirdparty/mast3r ... line. When pip tries to build curope from thirdparty/mast3r/dust3r/croco/models/curope, the build backend errors with:

ModuleNotFoundError: No module named 'torch'
So inside the isolated build env used by pip, torch isn’t visible even though it was installed earlier in the conda env. As a result, the Docker command from the current instructions doesn’t succeed on a clean build.

thank you for checking. I will check it later.
