user shouldn't be responsible for setting the `backups` parameter

[psx2]

Hi there,

I installed the software as instructed on this guide: https://pytti-tools.github.io/pytti-book/intro.html

Using the CLI command python -m pytti.workhorse conf=demo I get the following output after 18/30 iterations.

which produces this image

Any help would be appreciated! : )

I think you might be using an older version of the code here. Try upgrading to the latest version, instructions here: https://pytti-tools.github.io/pytti-book/Setup.html#uninstalling-and-or-updating

(should take just like 3-5 minutes)

[psx2]

No luck sadly, have tried an entirely fresh install too.

[dmarx]

can you generate a full stack trace and share it? set that environment variable HYDRA_FULL_ERROR=1 and share the output after reproducing the error. Also, please share your current settings (should have been spat out as one of the early log messages)

[dmarx]

are you still having issues with pytti?

I have this exact same issue when trying to run locally on my Windows 10 machine from a totally fresh install;

The first four images seem to render correctly, but the job always fails before step 12.

Would love to get this working locally, as image generation seems a fair bit faster than through collab.

ok, I totally see what the issue is now. As a temporary fix, you should be able to get around this by fiddling with the backups setting. Try setting that to 0 first: if you still get an error, try incrementing it higher starting at whatever it was previously set to when you go the error (e.g. if it was set to 5, try setting it to 6).

this setting frankly isn't something the user should be asked to set themselves. I'll try fixing this by having pytti-core compute a lower-bound for this setting, so users could set it higher than necessary if they want but never lower. I think that should fix it? we'll see.

[TomSlezakowski]

Thanks for the quick response, setting backups: 0 has it working now! & thanks for all the work on this in general, I'm only just scratching the surface, but a lot of fun and endless possibilities!

[dmarx]

glad to hear that fixed it! I changed a couple of the defaults a few days ago and that was one of em. I spent all day today wrestling with a really cryptic error that turned out to also be a consequence of the new defaults, so... whoops :/
