Hello,
I am facing a problem with local evaluation.
The command ‘dts challenges evaluate’ fails.
It says it can’t build a connect to docker daemon.

I attach the logs

Best regards,
Vadim Volodin

This might be a problem with your docker configuration. Could you send us the output of docker info, please?

This is a known problem – we are trying to understand the reason.

At the bottom here you can find a workaround:

Oh, I didn’t try the troubleshooting, thanks.
Here is docker info output https://drive.google.com/file/d/1XpVHTUgaOK8z1YsFfmrJlpPBxrMbKgkq/view?usp=sharing

Hello!

I’m facing error when running dts challenges evaluate. I tried it on all repos with “template” on github and it raises:

I did the troubleshooting. It helped. But for the second attempt it broke.

Hello
I’m facing a similar problem. When I first run dts challenges evaluate command (on the random template) it works fine. Then I change solution.py a bit and run dts challenges evaluate again and I failes with the problem

It seems like you may have an older version of duckietown-shell

If you are running locally, can you do
sudo rm -rf output && dts update

If you’re running in Docker, just run the second command.

Try this and see if it works?

I’m running locally and it did not help, I got the same error.

Could you explain what was changed in solution.py? Some lines inside are critical to correct scoring.

I just changed threshold value in our simple algorithm, just one number.

@polyprogrammist – can you remove the directory “output” and try again?

I think it’s a left over from before when we wrote the wrong permissions.

Alternatively use dts challenges evaluate --output DIR where DIR does not exist yet.

Hello, It works with removing an output. As soon as I understood, we recalculate a lot of data doing this way? If so, it’s easier to send submission to server than evaluate locally.

We changed the rights of the following directory and that worked: output/step1-simulation/challenge-evaluation-output/episodes
Could you make the permissions for it, please?
