Problem in the first version

I used Ubuntu18.04 to run it in terminl. But when i run the demo2_infer.py , i meet the following problem

2022-11-03 20:27:14.318140: I tensorflow/stream_executor/platform/default/dso_loader.cc:53] Successfully opened dynamic library libcudart.so.11.0

Strangely ,I didn't enconter this problem in demo1_gen_data.py with"from utils import *" and " import keras". what's wrong with it in demo2_infer.py and infer.py? Could you help me solve it ? Thank you very much .

Thanks [ydragon719] for you interest in our work !

It could be that this is a keras/tensorflow problem (but I'm not sure). I have found this:
keras-team/keras#14632

Thanks you! I have finished it. But I have a problem for the ground truth of the loop . How do you get the ground truth of the loop close decetion in kitti? The code in the project should be to obtain the true value of the network.
