Error when executing code 'data_prepare_s3dis.py'
I downloaded the S3DIS data set, created and moved the data/S3DIS/ folder, but the following error occurred when the 'data_prepare_s3dis.py' code was executed.
Any idea why I'm getting the 'original_ply' error? There was no original_ply in the s3dis dataset..
@IMSHJI @lmsdss I'm trying to run the data_prepare_s3dis python file, it shows me this error:
'''
Traceback (most recent call last):
File "data_prepare_s3dis.py", line 80, in
@youssef962
Did you download the s3dis dataset?
if you downloaded
As long as the path is specified correctly, the preprocessing code runs without problems.
@IMSHJI I downloaded the data and the problem is that the data_list array is empty! I printed it out and it was supposed to have the saved data but found it empty!
Maybe you need to add the full path？ dataset_path =‘ ’
I'm having the same error and i copied the full path and nothing changed! @IMSHJI how did you solve it? @lmsdss
@youssef962
I don't know.. Running the code in ubuntu seems to solve it, but The error that there is no array is considered to be caused by the Windows environment in my opinion.
@IMSHJI @lmsdss I'm trying to run the data_prepare_s3dis python file, it shows me this error:
''' Traceback (most recent call last): File "data_prepare_s3dis.py", line 80, in convert_pc2ply(annotation_path, join(original_pc_folder, out_file_name)) File "data_prepare_s3dis.py", line 47, in convert_pc2ply pc_label = np.concatenate(data_list, 0) File "<array_function internals>", line 6, in concatenate ValueError: need at least one array to concatenate ''' any ideas?
i got the same problem, have u find anyway to solve it?
Check your dataset path, maybe you should add ./ to redirect to your parent folder, makbe it will work.
Move the extracted folder to RandLA-Net/ directory and change the path to S3DIS/Stanford3dDataset_v1.2_Aligned_Version.
