TypeError: RadarPointCloud object not iterable

[sheetal39]

Trying to run the code and first ran into an error when calling from_file_multisweep() in nuscenes_generator.py under data_processing/generator. It was being called with an unknown parameter "merge." When I removed it, it led to the following error-

Traceback (most recent call last): File "train_crfnet.py", line 434, in main() File "train_crfnet.py", line 398, in main File "/home/iot/anaconda3/lib/python3.6/site-packages/keras/legacy/interfaces.py", line 91, in wrapper return func(*args, *kwargs) File "/home/iot/anaconda3/lib/python3.6/site-packages/keras/engine/training.py", line 1418, in fit_generator initial_epoch=initial_epoch) File "/home/iot/anaconda3/lib/python3.6/site-packages/keras/engine/training_generator.py", line 181, in fit_generator generator_output = next(output_generator) File "/home/iot/anaconda3/lib/python3.6/site-packages/keras/utils/data_utils.py", line 601, in get six.reraise(sys.exc_info()) File "/home/iot/anaconda3/lib/python3.6/site-packages/six.py", line 703, in reraise raise value File "/home/iot/anaconda3/lib/python3.6/site-packages/keras/utils/data_utils.py", line 595, in get got pcs and times <nuscenes.utils.data_classes.RadarPointCloud object at 0x7fc104a259b0> inputs = self.queue.get(block=True).get() File "/home/iot/anaconda3/lib/python3.6/multiprocessing/pool.py", line 644, in get raise self._value TypeError: 'RadarPointCloud' object is not iterable

Any help resolving this issue would be greatly appreciated!
