Cannot complete running "check_thor.py" because of ConnectionResetError.

[maguro27]

I met the ConnetionResetError when I ran "check_thor.py" after running the docker container based on slightly modified Dockerfile. The main modification of the Dockerfile is that I change the docker image from nvidia/cuda:9.0-cudnn7-devel-ubuntu16.04 to nvcr.io/nvidia/pytorch:20.12-py3 because my GPU machine does not match the NVIDIA driver version (namely, use cuda 11.1 because of using NVIDIA RTX A6000) The full error message is as follows,

Although I inserted time.sleep(0.01) before downloader.py in line 18, I cannot resolve this error. How do I fix it? Please lend me your hands.

@maguro27, have you looked at this https://github.com/devpi/devpi/issues/597?

I would also suggest starting a fresh docker container in shell mode and manually installing everything in the Dockerfile one-by-one. This is much easier to debug than directly building docker images.

[maguro27]

@MohitShridhar Thank you for replying!

I didn't meet the ConnectionResetError when I installed the newest version of ai2thor of pypi. However, I met another error. If I continue to suffer from the new error, I make a new issue. Thank you for the advice!

[maguro27]

I couldn't find the cause of the ConnectionResetError. However, I found another solution.

1. download the ai2thor environment files directly from http://s3-us-west-2.amazonaws.com/ai2-thor/builds/thor-201909061227-Linux64.zip.
2. unzip the ai2thor environment files.
3. move the unzipped files to ~/.ai2thor/release/.

Although I complete running the check_thor.py, I get another error/warning.

Everything works!!!

Is it a critical error/warning?

[MohitShridhar]

@maguro27 these warnings can be ignored. (300, 300, 3) Everything works!!! is all that is important.

[maguro27]

@MohitShridhar Thank you for the reply! I really really appreciate you.
