At a minimum, these are the issues I found.

1. you need to write to the depth buffer (otherwise how would anything occlude?)

   so remove gl.depthMask(false)

2. you need to gl.flush the OffscreenCanvas because being offscreen, one is not automatically added for you. I found this out by using a normal canvas and adding it to the page. I also turned on drawing by commenting out gl.colorMask(false, false, false, false) just to double check that your boxes are drawn correctly. I noticed that when I got something kind of working it behaved differently when I switched back to the offscreen canvas. I found the same different behavior if I didn't add the normal canvas to the page. Adding in the gl.flush fixed the different behavior.

3. depthSort was not working

   I checked this by changing the shader to use a color and I passed in i / NUM_SPHERES as the color which made it clear they were not being sorted. The issue was this

First rank the rows by their ENRT_CVG_STRT_DT per person (assumed identified by PAPF.PERSON_NUMBER). Then filter on rows that are top.

The pytorch error you get means "you can only call backward on scalars, i.e 0-dimensional tensors". Here, according to your prints, policy_lossis not scalar, it's a 1x4 matrix. As a consequence, so is policy_loss + 0.5 * value_loss. Thus your call to backward yields an error.

You probably forgot to reduce your losses to a scalar (with functions like norm or MSELoss ...). See example here

The reason it does not work is the way the gradient propagation works internally (it's basically a Jacobian multiplication engine). You can call backward on a non-scalar tensor, but then you have to provide a gradient yourself, like :

• Ctrl+H
• Find what: (?:^HI\*BBQ\b.+?~\RHI\*BB|\G(?!^).*?\bBB)\KQ\b
• Replace with: B
• CHECK Match case
• CHECK Wrap around
• CHECK Regular expression
• UNCHECK . matches newline
• Replace all

Explanation:

You should be able to pass some environnement variable from you run command to your CMD before the "cmd" is triggered. To do such, try using the '-e' clause this way (not tested, but should work):

I think sometimes it can be helpful to generalize a bit when solving these kinds of problems. Consider the function below:

Because that's how atomic group works. The idea is:

at the current position, find the first sequence that matches the pattern inside atomic grouping and hold on to it. (Source: Confusion with Atomic Grouping - how it differs from the Grouping in regular expression of Ruby?)

So if there is no match inside an atomic group, it will iterate through all options. You can use conditionals instead:
