Open qiang-sean-liu opened 1 year ago

qiang-sean-liu commented 1 year ago

Hi, I downloaded the sensor data. And I checked that the bytes of each zip file the same as listed at https://www.nuscenes.org/nuplan#download. But when I tried running unzip, it complained:

" End-of-central-directory signature not found. Either this file is not a zipfile, or it constitutes one disk of a multi-part archive. In the latter case the central directory and zipfile comment will be found on the last disk(s) of this archive. unzip: cannot find zipfile directory in one of nuplan-v1.1_test_camera_0.zip or nuplan-v1.1_test_camera_0.zip.zip, and cannot find nuplan-v1.1_test_camera_0.zip.ZIP, period. "

Please advise. Thanks!

Hi @qiang-sean-liu,

This is a known issue. Try extracting it using tar -xf data.zip

Is there a way to check if the extraction is complete successfully? Is there a list of files or a hash or anything like that?

patk-motional commented 1 year ago

There is the metadata file that lists the log files that the sensor data corresponds to. You can confirm that the file was downloaded correctly with the hash displayed on the website. However, we do not provide individual hashes for every file in each zip file

Could you provide the tree of the entire dataset? I think it would be much more helpful if I could just compare the diffs between my tree and your tree outputs.
