Specifically, when I run python fluidlab/run.py --cfg_file configs/exp_gathering_easy.yaml --record
it reports:

There are some other issues with renderred_type, but I assume that following the latter_art.env, we could solve this~
Is there a plan to have documentation about how to generate the paper results?
Best,

I am trying to run fluidlab on a remote pc. As such, I am trying to save the frames generated using the save variable in fluidlab.optimizer.recorder.py. However, I am running into an issue regarding the display:

(fluidlab) cewang@blackcoffee:~/FluidLab_SLURM$ python fluidlab/run.py --cfg_file configs/exp_latteart.yaml --record --renderer_type GL
[Taichi] version 1.1.0, llvm 10.0.0, commit f5bb6464, linux, python 3.7.13
[Taichi] Starting on arch=cuda
===>  TaichiEnv created.
===>    60000 particles of     milk  nowhere added.
===>    55480 particles of   coffee cylinder added.
===>  LatteArtEnv built successfully.
qt.qpa.xcb: could not connect to display
qt.qpa.plugin: Could not load the Qt platform plugin "xcb" in "/home/cewang/miniconda3/envs/fluidlab/lib/python3.7/site-packages/cv2/qt/plugins" even though it was found.
This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.

Available platform plugins are: xcb.

Aborted (core dumped)

I am wondering if there is a headless mode where I can bypass the cv2.imshow, or will I have to implement it myself. Thank you!

Hi, I'm trying to run the example in the readme file. It is however complaining about no vulkan for ggui. I'm wondering if Taichi requires this for visualization. It would be helpful if some instructions could be added here :)

Hi, I made a 3D model of a jug (.obj), put it into asset/raw and I am using it as an end-effector(agent).
However, I found that the volume of the liquid is shirinking during the simulation. I guess it is not just the decreasing gap between particles, as it does not happen with a provided cup model.

Do you have any advice or is there any stable way to build a 3D model for Fluidlab?

Hi! Thanks for your great work!

I am wondering whether the camera ready version will be released?

Hello! I followed all the installation instructions(except GLRenderer) and faced the following error message while trying Let's Rock first step.

Could you take a look into this?``
