Perceptilabs Does Not Start

Bugs and Issues
#1

Hello, I ran through the intro video on how to install Perceptilabs, created a new conda env, installed Perceptilabs, and tried to start when I get (after a few ‘could not load’ cuda library warnings) :

PerceptiLabs: Starting
PerceptiLabs: Waiting for services to listen on these ports:
PerceptiLabs: rygg on port 8000
PerceptiLabs: fileserver on port 8011
PerceptiLabs: frontend on port 8080
PerceptiLabs: Waiting for services to listen on these ports:
PerceptiLabs: rygg on port 8000
PerceptiLabs: fileserver on port 8011
PerceptiLabs: frontend on port 8080

ad infinitum. The first time I ran it, Windows popped up with the ‘allow access to your public/private networks’ prompt, but after accepting that still nothing opens in a new browser window. Nothing comes back if I run netstat -na | Select-String "8000" in Powershell (or any of the other ports), before running perceptilabs, so I assume this means that they’re not being used. Does anyone have any ideas as to how to troubleshoot what might be going on?

Hi @Serotonin,
Sorry to hear that you are having issues starting the tool!

Sounds like something may have gone wrong with the installation, could you run the tool as “perceptilabs -v=3” (it enables a lot more messages) and cop/paste everything in the terminal over to here?
Then we can take a look and see what broke :slight_smile:

All the best,
Robert

Hi,
Thanks for the logs!

It looks like something with the Django package is crashing, which version of Django do you have in that environment (you can see all packages through “pip list”)?
Also, did you install PerceptiLabs in a new environment? :slight_smile:

#5

Django 3.2
django-cors-headers 3.7.0
django-http-exceptions 1.4.0
django-request-logging 0.7.3
djangorestframework 3.12.4

Yes, I created a new conda env, just as in the video. Originally, running
perceptilabs
after installation did not find the file (as pip didn’t install it to my \envs\pl environment), so I either have to add user\AppData\Roaming\Python\Python37\Scripts to my PATH or manually locate the file when running in Powershell.

#6

Hi @Serotonin,
We took a deeper look and it seems like you may may have a host name (computer name) that’s not valid utf-8:

retrieving CUDA diagnostic information for host: ▀-Endorphin

(The little black square there is the non-valid symbol).

For some reason, Django does not like it and crashes, which seems to be a limitation in Django that we can’t do much about.
My best suggestion would be to update your computer name so it only contains “standard” symbols.

Hope that helps!

#7

Bingo! Thanks for the help and sorry for my stupid naming conventions!
