I have a dataset of ~24GB and I've tried multiple times uploading it with the sync function.

• The cache doesn't work, it attempts to download the dataset every time.
• It "misses" some files somehow. So once the job runs it fails due to missing files.
• I've ran verify afterwards (from the machine I used to upload the data) and it says it's all good. However, once I inspect the zip files on the server (look for the files in the specific zip the state json says they're in) the files are indeed missing.

Once I used clearml-data add --folder * API everything works correctly (though all files recursively ended up in the root, I had luck all were named differently).

@<1523701205467926528:profile|AgitatedDove14> Any ideas on this issue? Thanks!

sorry missed that one

just making sure the dataset itself contains all the files?

Once I used clearml-data add --folder * CLI everything works correctly (though all files recursively ended up in the root, I had luck all were named differently).

Not sure I follow here, is the problem the creation of the dataset of fetching it? is this a single version or multiple versions?

OSX 12.5.1
Python 3.8.1.
Clearml 1.13.1

"clearml-data add --folder ./*" always flattens everything, I have that reproducible 100%.

Single version. The issue seems to be the creation. If I use "clearml-data sync --folder ." it says it uploaded all the files. Running "clearml-data verify --folder ." says it's all good. Metadata on the WebUI reports the expected number of files. However, once I extract the zips (or download the dataset through Python API or CLI) not all the files are there.

"clearml-data add --folder ./*" seems to fix this issue though it doesn't preserve my directory structure so I'd have to write a script to do it manually, but that shouldn't be necessary as clearml-data sync should already be doing that as far as I understand but it seems to have a bug there.

and all the files are registered in the metadata? coulf you add --verbose to the sync command to see what it is doing

This is also odd, it should Not flatten the folder structure. What is your OS / Python / clearml version?
Is this reproducible ? if so, how could we reproduce and debug?

Clearml 1.13.1

Could you try the latest (1.16.2)? I remember there was a fix specific to Datasets
