Hi TimoStoff

[wuyy1234]

Hi, T. Stoffregen, first thank you for providing me the esim_config_generator which is new to the research field. I follow the guidance in the README and generate some bags using your code. But I am confused with the content and size of the generated bags. Why the size of these bags are just 4.1KB while the first bag have the size 600MB+? Are these bags dependent on the first bag in some way? Accoring to the code, it seems that all these bags are independent of each other.

No error during the execution, below is the warning output. ALL generated bags provide the same warning output.

Hi Alan,
Something has definitely gone wrong here, the bags are supposed to be much bigger than this, in the hundreds of MB each (this is why I am not hosting the training dataset itself). Could you please send me some of your scene and simulator config files? Maybe the issue is there. Otherwise it's probably something in ESIM, I have also previously encountered issues where there is a failure without any error resulting in empty rosbags.

Hi, T. Stoffregen, thanks for your reply.
The scene and config files are the same as the files in the given links https://drive.google.com/drive/folders/1ILoFnR5BHR17F0VGEzR0JIBfisw1nkc4?usp=sharing.
I only modify the path /home/wuyy1234/data/train2017/ which is shown below:

Other than that, no other changes were made.
I conduct two different tests for the generator:

1. Firstly I generate 000000002_out.bag and 000000003_out.bag one by one separately. The sizes of them are 686.6MB and 1GB.
2. Then I generate 000000002_out.bag and 000000003_out.bag together at one time and the sizes of them are 686.6MB and 4.1KB.
   It's clear that we can't process more than one configs at one time. It can produce empty bags for some configs.

Hello , I also encountered a similar problem, have you solved this problem?
