Where is my data gone?

[r0f1]

Hi, I tried adding two files to dvc. One of them was added (experiment123_45.6_detecions2.csv), one of them vanished (detections.csv).

The series of commands was the following:

user@machine/projects/unsupervised$ dvc add data/experiment123/detections.csv data/experiment123/experiment123_45.6_detecions2.csv
 50% Add|█████████████████████████████████████████████████████████████                                                             |1.00/2.00 [00:00<00:00,  4.11file/s]

ERROR: unexpected error - [Errno 1] Operation not permitted: '/projects/unsupervised/.dvc/cache/7c/0396376f7180e359c7eb8b275b84ad.DgH8CkuMWR6TH7ecmJpTYX'

Having any troubles? Hit us up at https://dvc.org/support, we are always happy to help!

There was an error, so I tried adding files one by one:

user@machine/projects/unsupervised$ dvc add data/experiment123/experiment123_45.6_detecions2.csv
100% Add|██████████████████████████████████████████████████████████████████████████████████████████████████████████████████████████|1.00/1.00 [00:01<00:00,  1.15s/file]
To track the changes with git, run:

        git add data/experiment123/.gitignore data/experiment123/experiment123_45.6_detecions2.csv.dvc

user@machine/projects/unsupervised$ dvc add data/experiment123/detections.csv
100% Add|██████████████████████████████████████████████████████████████████████████████████████████████████████████████████████████|1.00/1.00 [00:00<00:00,  3.77file/s]

ERROR: output 'data/experiment123/detections.csv' does not exist

The result:

user@machine:/projects/unsupervised/data/experiment123$ ls -a
. .. experiment123_45.6_detecions2.csv  experiment123_45.6_detecions2.csv.dvc  .gitignore

How do I restore data/experiment123/detections.csv ?

Ah, this is a duplicate of #2992.
