Cannot find mesh

[Jun Zhou]

Hello,

Thanks for your exciting work.

I ran the interactive visualizations raisimUnity/linux/raisimUnity.x86_64 in the artigrasp directory and clicked Connect bottom. However, nothing was shown in the window, but error texts System Exception: Connot find mesh from the resource directories = ./meshes/right_wirst.stl.

Do I lack some resource files?

Looking forward to your reply!

BR!

Hi Jun,

Thanks for your question. It's a bit strange with this problem. Have you checked the Auto-connect option?

And have you changed anything? Does the runner_eval.py shows any error?

Best,
Hui

Hi Hui,

Thanks fro you reply. I had checked the Auto-connect option but got the same problem.

I followed INSTALLATION to configure my environment.

The runner_eval.py seem to be normal.

But the command sudo apt install libvulkan1 mesa-vulkan-drivers vulkan-utils was not passed. Is this the key to the problem?

Sincerely,
Jun

Hi Jun,

VulKan is the render API of raisim. As you can run runner_eval.py normally, the problem should come from the simulation visualization side. The failure of sudo apt install libvulkan1 mesa-vulkan-drivers vulkan-utils may be the reason. Could you try to pass this command and check whether this solve the problem? Please tell me if it doesn't help.

Best,
Hui

Hi Hui,

Thanks for your advice. Yesterday, I tried to install vulkan-utils by the command sudo apt install valkan-utils. But failed. I think that valkan-utils cannot be install on Ubuntu 22.04.

Today, I change the OS of my PC to Ubuntu 20.04, and valkan-utils is installed successfully. It seems all commands in INSTALLATION.md are passed. However, RaisimUnity still shows nothing but the error text, which is same with the case I occurred yesterday.

Here are the information of my PC.
CPU: i7 8700
GPU: RTX 2080Ti
OS: Ubuntu 20.04.6
CUDA: 12.2

Hi Jun,

I have just checked the resource files and found I mistakenly forgot to upload .stl files. I have just loaded them so you should be able to see the visualization now after git pull.

I am sorry for the mistake and thank you for pointing this out! Please tell me if you have any other questions. Otherwise I will close this issue.

Best,
Hui

Hi Hui,

I cloned the latest repository and ran the commands again. The RaisimUnity showed a different error which can be seen as follow.

Note that, the .stl file name is different. That means we are on the right direction. 👍
