Currently, during the replication process, I encountered the following issue:

when I run the command python main.py -y config/waymo-1137.yaml -p "Add a Benz G in front of me, driving away fast." for testing, I receive the following error:

FileNotFoundError: No such file: '/home/lferris/ChatSim/results/cache/1137_demo_2024_07_09_11_04_41/blender_output/0/RGB_composite.png'

The McNeRF has already been fully trained, and I have also called the valid OpenAI API.

[LFerris123]

Has anyone encountered the same issue? What solutions do you have?

[yifanlu0227]

Is there any files in /home/lferris/ChatSim/results/cache/1137_demo_2024_07_09_11_04_41/blender_output/?

[LFerris123]

Thanks for reply!There is no files in /home/lferris/ChatSim/results/cache/1137_demo_2024_07_09_11_04_41/blender_output/

[yifanlu0227]

Run the blender rendering separately to see if it works. You can follow the Blender utils Readme

You can just run the command in usage section if everything for chatsim is set.

[LFerris123]

I checked the output folder and found no valid Blender output files, so I reconfigured the documents according to the Blender utils documentation you provided. However, I am currently encountering the following issues:
Currently, according to the documentation, there will be three different Blender installation locations. The first one is as shown in the Installation commands, which installs Blender in the background folder (however, there are no required files for subsequent use here, which is clearly incorrect). The second is in the Blender folder under the foreground files that come with the project files (this should be the correct Blender installation location). The third is the path under the Blender utils README file, as shown in the figure below: Which Blender path should be used for successful rendering?

[yifanlu0227]

Hi, sorry for the confusion. Just make a alias to you installed blender, no matter where it is installed.

alias blender='<SOMEWHERE>/blender-3.5.1-linux-x64/blender'
alias blender_python='<SOMEWHERE>/blender-3.5.1-linux-x64/3.5/python/bin/python3.10'

[yifanlu0227]

If you followed the project's README, <SOMEWHERE> would be ChatSim/chatsim/foreground/Blender

[yifanlu0227]

I update the README, and hope it is more clear.

[LFerris123]

Thank you for your reply! I have individually tested the Blender module according to the setup in the Blender utils Readme, and it can now produce the same valid output as documented. However, when I directly run "python main.py -y config/waymo-1137.yaml -p 'Add a Benz G in front of me, driving away fast.'", I still encounter the same error.

[LFerris123]

Has anyone encountered the same issue? The result file blender_output is empty

[LFerris123]

The blender rendering can run separately,but when I run python main.py -y config/waymo-1137.yaml -p "Add a Benz G in front of me, driving away fast.",I find that the file "blender_output" is still empty

[yifanlu0227]

Probably it is due to OOM, reduce multi_process_num in the yaml file. You can also check the log files under result/cache/

[xyyu-callen]

Totally the same issue I encountered with you, do you have found some solutions?

[xyyu-callen]

Setting multi_process_num equal to 1, this issue disappears.

[wmkai]

Setting multi_process_num equal to 1, this issue disappears.

I met the same error. But after I set multi_process_num to 1, the error still exists.

[yifanlu0227]

could you guys share the log file？@wmkai @xyyu-callen

[yifanlu0227]

Blender fails to render the images. Well, you can see we run the blender rendering command following those lines

ChatSim/chatsim/agents/foreground_rendering_agent.py

Line 307 in 923b20c

command = (

Could you run it manually? You can use existing cache dir, set -- {start_frame} -- {end_frame} like -- 0 -- 1.

Just remove the > {log_file} to see the log in terminal and if there is any rendering output

[wmkai]

I tried to run chatsim/foreground/Blender/blender-3.5.1-linux-x64/blender -b --python chatsim/foreground/Blender/utils/blender_utils/main_multicar.py --results/cache/1137_demo_2024_09_10_07_51_44/blender_yaml -- 0 -- 1.

Then it shows 'chatsim/foreground/Blender/blender-3.5.1-linux-x64/blender: error while loading shared libraries: libXrender.so.1: cannot open shared object file: No such file or directory'.

So I use apt-get install to install libxrender1, libxi6, libxkbcommon0, libsm6. It works!
