How to render the environment?

[77asadian]

Hi,

I want to render the base code that I performed here:

Can you please help me with this?

Thank you for opening this @77asadian. So, you are running this inside a jupyter notebook right?

Yes, I'm running this in jupyter notebook.

Can you share your OS version and a screenshot of the shell where you started jupyter notebook?

[77asadian]

I'm using Windows Home 21H1. Here is the screenshot you asked for:

I just tested it and in my configuration it works:

I am using the python notebook example file provided in our repo: https://github.com/diambra/arena/blob/main/examples/diambra_arena_gist.ipynb

It seems there are problems with the widget control, let me check.

[alexpalms]

But no, I have the same message/warning here and everything works. Can you please comment the rendering and see if, on this same console, it prints out logs demonstrating it is proceeding?

[alexpalms]

You should be seeing something like this:

[77asadian]

There was no rendering window opening for me. I commented the render line and there is no output log.

Two things: 1) be careful with that comment since it is not indented and can give problems, just to be sure, remove the line

2) I am referring to comments in the shell/console where you launched jupyter notebook (where you typed diambra run ...)

[77asadian]

I'm seeing this:

[alexpalms]

I'm seeing this:

Looks all good. Please at the bottom confirm there is something like "Waiting for fight to start"

Don't mind that thing where you put an arrow, it's normal

Don't mind about that thing where you put an arrow, it's normal

Is it this?

[alexpalms]

Yes, but please share also the most recent logs/outputs

[77asadian]

There are so many codes here. I hope this would help.

[alexpalms]

everything seems to be executed properly. Add print("Reward = ", reward) before the if done: condition in the script

then run the script again and let's see if it is correctly running

[77asadian]

print("Reward = ", reward)

We have some rewards here.

[alexpalms]

yes, so everything is working.

It is strange you are not able to see the rendered screen. Need to check it on Win. You're not using a virtual machine or a headless configuration right?

[77asadian]

No, my OS is not running on a virtual machine. I'm using a Lenovo Legion 5 laptop.

Can you do the following test? Add the following lines at the top of your jupyter script:

import os
print(os.getenv("DISPLAY"))

and past here the output

[77asadian]

It seems there is no display.

[alexpalms]

Ok so that is the problem, cause we use that check to decide if showing or not the render image. But it could be we need a different check for windows, I'll carry out some tests and let you know.

In the meantime you can use it without rendering.

Thank you for your help. I'm looking forward to your response.

Hey @77asadian, just pushed a new diambra-arena version (https://pypi.org/project/diambra-arena/ v2.0.0rc8) implementing the fix that solves this (tested on Win), this is the commit: https://github.com/diambra/arena/commit/35bde2bf91de89a4cf48d62f5f436e278cbb9a39

You should update your python environment installing the latest version with pip install -U diambra-arena and re-run the simplest example (diambra_gym_gist.py) with env.render() active.

Please confirm that you're able to see the rendering so that we can close the issue
