Exception: There should be either 2 or 4 but we have [(side-R31-Gr, side-F24-Rd)]

[guinasc2]

Sorry to bother you again, but I need help. Now the solver scans the cube and returns a JSON with the readings, but then it returns me the following error:

What should I do?

[dwalton76]

There is a file in /tmp/ called rubiks-color-resolver.html, can you attach that file to the issue here?

[guinasc2]

I can't find this file anywhere. Is there any /tmp/ inside another folder?

[dwalton76]

It should be /tmp/rubiks-color-resolver/rubiks-color-resolver.html

[guinasc2]

I still can't find it. Do you think I may have skipped any steps during the installation?

[dwalton76]

my bad, I just looked at the code and at some point I stopped writing the file to /tmp and started writing it in the current directory :( Look in the directory with mindcuber.py for a rubiks-color-resolver.html file.

[guinasc2]

I didn't find it in the directory. Do I have to do anything besides run the code for it to appear?

[WasabiFan]

@dwalton76 Is there any reason this file wouldn't be there?

@guinasc2 Can you show us the output of the ls command?

[dwalton76]

@guinasc2 can you re-install rubiks-color-resolver per the README at https://github.com/dwalton76/rubiks-color-resolver

Just to make sure you are running the latest and greatest

[mm738]

Same issue. Everything is installed per the instructions. Any ideas from here?

[dwalton76]

@mm738 please attach the rubiks-color-resolver.html file, that has the info I need to try to figure out what happened.

[mm738]

@dwalton76 sure, what are the steps to enable it?

Currently it is not created. The below yields nothing.

robot@ev3dev:~/ev3dev-lang-python-demo/robots/MINDCUB3R$ sudo find / -name "rubiks-color-resolver.html"

[dwalton76]

@mm738 that is really weird. If you run this from the directory where your rubiks-color-resolver.py resides does it create the rubiks-color-resolver.html file?

The values above are from your RGB json output. The resulting html file is
rubiks-color-resolver.html.gz

which shows the initial cube colors as:

Those are some pretty strange colors:

• there appear to be 3 white centers and 3 yellow centers?
• the entire back face is white?

Can you post a picture of the cube so I can get an idea of the color scheme?
