4 years ago The problem might be due to the fact you're using a virtual machine, which is not fully supported for our code. For the training dir path, please set up the path you want the code to save data before starting the data collection process!
Hello there,
I am trying to use your code to generate data for training a CNN of my own. However, I can't seem to do it. Every time I run the collect_python.py file (in the correct directory), the process seems to be running, but i can't find the generated data anywhere. The TRAIN_DIR path leads to a directory that remains empty.
In the command line, other than the error messages caused by the fact that it couldn't open the joystick force feedback, there were these two error messages, and i thought perhaps it was due to them that I can't generate data properly:
[ERROR] [1591312435.843784, 2911.803000]: Spawn service failed. Exiting.
this leads to this red message: [hummingbird/spawn_hummingbird-2] process has died [pid 7162, exit code 1, cmd /opt/ros/melodic/lib/gazebo_ros/spawn_model -param robot_description -urdf -x 0.0 -y 22.0 -z 0.1 -model hummingbird __name:=spawn_hummingbird __log:=/home/fechec/.ros/log/381c0d20-a41b-11ea-972f-080027ba532d/hummingbird-spawn_hummingbird-2.log]. log file: /home/fechec/.ros/log/381c0d20-a41b-11ea-972f-080027ba532d/hummingbird-spawn_hummingbird-2*.log
By looking up the log file, the error seems to come only from the spawn service. Here is what one iteration over the background pictures looks like:

If somehow you guys can help me solve this issue, I would greatly appreciate it. I have been looking around for quite a while without finding what was the problem.
Thank you very much!

P.S. I'm a big fan of you work! It's really cool :)
