Improving Rendering & Processing Speed with AWS about zpy

[tgorm1965]

Ok my username is tgorm and I'd love some free credits. I've tried uploading using zpy upload sim but i get the following error: No such command 'sim'. Would love a fix for this please.

We have a CLI that allows you to upload a local blender simulation and generate images in the cloud. More info on the CLI in our docs. You can also view and download these datasets on our webapp. A quick caveat though: we just pushed a bunch of changes to the CLI & WebApp today, so it might be buggy (we love feedback).

The way we see it the local device is just intended to be used for debugging. We provide the ability to generate images at scale from a sim using our configured backend using our WebApp (https://app.zumolabs.ai) and cli (https://zumolabs.github.io/zpy/cli/about/).

Through the addon you should be able to export the sim and then using the cli you should be able to upload the sim and generate datasets from the sim.

zpy sim upload <sim_name> path/to/exported/sim.zip
zpy dataset generate <dataset_name> <sim_name> <num_frames>

then you should be able to view the dataset on
https://app.zumolabs.ai/datasets

Let me know when you create an account and we can enable 5k in free generation credits for you.

You can export a local simulation by hitting the Export Sim button on the zpy addon panel:

This new cli format went live earlier today. I would make sure your zpy-zumo python package is at version 1.3.0

[tgorm1965]

Yep, I just did a new pip install of zpy-zumo, so I'm unsure if that is the issue. Is this what you mean or do you mean the package in. Blender?

[nponte-zumo]

Yes you will also need to update the zpy-zumo the addon is using as we export more information from scenes from before.

The error on the command zpy sim upload no such command sim is probably due to our new CLI swapping from zpy upload sim to zpy sim upload

[tgorm1965]

Ok I will do that. Also another question regarding your generation times. If I want a full HD 1080p image and roughly 75% of the image needs to be segmented into categories, how long would something like that take per sim step in your experience? It's taking close to 10mins per step for me currently

[nponte-zumo]

After uploading the sim you can see the amount of time in seconds it will take to generate one step under time. Hard to tell without running it and seeing how the objects are loading and such.

[tgorm1965]

Ok sounds good. And if I run out of generation credits how much do they cost moving forward?

[nponte-zumo]

Still something we are figuring out ourselves. Would love feedback to what would feel good from a user perspective.

Our current implementation is some cost per time spent running on the machines which is correlated to our own spending costs.

Hey, I'll need to try itout before giving feedback I think.

Im currently getting this error when trying to run the sim: raise JSONDecodeError("Expecting value", s, err.value) from None
json.decoder.JSONDecodeError: Expecting value: line 1 column 1 (char 0). Could you help me resolve this please

[nponte-zumo]

The sim failed to ingress so you will be unable to generate images from it until the sim ingress is successful.

I believe this error is related to the sim being exported with the old version of the addon 1.2.3 as you can see above.

@tgorm1965

Just added backwards compatibility for old scenes so you should be able to upload the current sim you have and have it ingress successfully if you want to give it another shot.
