Thanks for sharing the code. However, I got the following error: ../data/2011_09_26_drive_0056_extract.p ../data/2011_09_26_drive_0084_extract.p ../data/2011_09_26_drive_0086_extract.p ../data/2011_10_03_drive_0034_extract.p Traceback (most recent call last): File "/home/hao/Desktop/ai-imu-dr/src/main_kitti.py", line 482, in dataset = KITTIDataset(args) File "/home/hao/Desktop/ai-imu-dr/src/main_kitti.py", line 119, in init super(KITTIDataset, self).init(args) File "/home/hao/Desktop/ai-imu-dr/src/dataset.py", line 56, in init self.set_normalize_factors() File "/home/hao/Desktop/ai-imu-dr/src/dataset.py", line 96, in set_normalize_factors pickle_dict = self.load(self.path_data_save, dataset) File "/home/hao/Desktop/ai-imu-dr/src/dataset.py", line 151, in load pickle_dict = pickle.load(file_pi) AttributeError: Can't get attribute 'SO3' on <module 'liegroups.torch.so3' from '/home/.conda/envs/myenv/lib/python3.6/site-packages/liegroups/torch/so3.py'>

I have installed liegroups package and passed the pytest. Just wonder whether anyone else has encountered the same error before.

Thanks!

I have the same problem. From the official guide of torch, this problem may caused by improper saving method of model. I've not yet solved the problem. here's some links may help you and if you make any progress, please contact me. https://stackoverflow.com/questions/27732354/unable-to-load-files-using-pickle-and-multiple-modules https://discuss.pytorch.org/t/error-loading-saved-model/8371

have you solved the problem?

fjjjj123e4 commented 4 years ago

finally i solved the problem such silly error is caused by the lib 'liesgroup' in the latest version of this package, the author modified the name of SO3 (into SO3matrix), which caused the attribute error you can git this commit https://github.com/utiasSTARS/liegroups/tree/01a1554bcc971907bdd3584eed4cd5acee3afc12

Yes, this solved the problem :) Thanks a lot for your help!
