About collision _label/scene_0110/collision_labels.npz in Dataset

[yanjh97]

Hi, I encountered an error as follows:

import numpy as np
data_root = '/media/wind/Share/DataSet/GraspNet1Billion'
collision_label = np.load(os.path.join(data_root, 'collision_label/scene_0110/collision_labels.npz'))
print(collision_label.files)
print(collision_label['arr_8'].shape)

Output: ['arr_0', 'arr_4', 'arr_5', 'arr_2', 'arr_3', 'arr_7', 'arr_1', 'arr_8', 'arr_6'] OSError Traceback (most recent call last)

Hi, does this error occur on other files either? Maybe you can check whether the file is complete.

[yanjh97]

No, this is the only one. And 'arr_0' ~ 'arr_7' in this file are normal.

[chenxi-wang]

I had a try and did not see this error. Maybe you can check whether there is something wrong when downloading.

[yanjh97]

OK. Thanks for your reply.
