thank you for share your project.
i prepared all the repository, and when i run demo.py in Pycharm:
if __name__ == "__main__":
play_sequence()
it is not error, but the plot dose not move and generate many empty plots.
i dont know how to submit pic in git, but i also waiting for your reply.
thanks

Hello, I followed the installation steps, the only difference would be that I used python3 here: "python setup.py install" instead of python.

I compiled the dr_spaam_ros pack and it tried to launch the node however I was met with the following weird error.

`... logging to /home/pedro/.ros/log/af40bed4-9243-11eb-a885-8d8ffcb1084e/roslaunch-pedro-Legion-Y540-15IRH-36436.log

Where did I mess up for it to be looking into: '/home/dan/git/DR-SPAAM-Detector_private/dr_spaam/ckpts/dr_spaam_e40.pth'?

Hello, thanks for the great contribution. I have tried the model on nvidia xavier NX.

When I try rostopic hz /dr_spaam_detections, I get around 0.2Hz instead of 20Hz++ that shown in the documentation. Do you have any ideas on that?

i comments plt.pause(0.001)
and uncomments plt.savefig('xxxxxxx/output/frame_%04d.png' % i)
then i run the project in terminal with python demo.py --dets
three time information displayed:
inference time (model: DR-SPAAM, gpu: True): 13.697982 ms (73.0 FPS)
inference time (model: DROW, gpu: True): 12.038951 ms (83.1 FPS)
inference time (model: DROW-T5, gpu: True): 30.621982 ms (32.7 FPS)
and then, it is just running and nothing in xxxxxxx/output

Hi guys, Great work! Just wanted to let you know, I am on commit 56ded71 (master), followed the install instructions. When running python bin/demo.py --dets, the following error pops up:

 (master)$ ipython -i bin/demo.py -- --dets

TypeError: __init__() got an unexpected keyword argument 'area_interp'

removing the area_interp=False, arg from the function call fixes the error, I assume it's just an untracked API change.

i want to use this project for my own data, i just have the .bag files generated by laser.
is there some python scripts or something to do this?
