V2 - CSV Export - CSV is blank #797

Open JCAAUSFRA opened 5 years ago

JCAAUSFRA commented 5 years ago

Describe the bug When I export the labelled data the CSV file remains blank.

The system tells me the export was successful. It correctly exports the images and generates the CSV file, it is just empty with Image Name, ymin/max, xmin/max, label.

To Reproduce Steps to reproduce the behavior:

  1. Label Data
  2. Ensure export is in CSV
  3. click the export button
  4. navigate to export file and Verify CSV file export. it should be empty

Expected behavior I thought there the image name, coordinates and label within this csv file.

Screenshots If applicable, add screenshots to help explain your problem.

Looks like there is one line of data in the csv from the screenshot. How many regions were labeled in the dataset?

JCAAUSFRA commented 5 years ago

Correct. Only one line was extracted in the data. Total number should be 1100ish

@JCAAUSFRA - Are you source assets linked from local file system assets? or a cloud source? Can you share a minimal example that reproduces? I was not able to reproduce with our test data sets.

JCAAUSFRA commented 5 years ago

Local asset. But it is a server on our internal network, not on my personal computer.

I played around with the export functions and have found some interesting information that might get to the bottom of the issue.

In order to explain in I need to give you the timeline:

  1. started a new project
  2. Tagged around 1000 images
  3. Changed the export location and export format to CSV from JSON
  4. Tried to export project in CSV and got nothing
  5. Visited another image and tagged a new image.
  6. Exported the project in CSV. Got one image
  7. visited and tagged another 5 images

  8. Exported the project in CSV and got all 6 images exported (1 from previous and 5 from current round)

    It is like the VoTT export system is only referencing the images I visited after the export format change rather then going back and exporting ALL previously visited and tagged images.

Hope this explanation helps and sheds some light.

JCAAUSFRA commented 5 years ago

Had more of a play around. I decided if the exporter just needs me to revisit the images then I could just scroll back through all the images and the CSV file would populate.

However this did not occur. It seemed to re-write the file to no detection.

wbreza commented 5 years ago

@JCAAUSFRA - The export will always restart and process all images in your project based on your export settings. Which option are you choosing? All assets, visited? or only tagged assets?

If you are able to reproduce a smaller use case it will be easier to diagnose the issue. Feel free to email me - wallace.breza@microsoft.com

JCAAUSFRA commented 5 years ago

Hi @wbreza,

I managed to reproduce it on another project.

Essentially if you change the export file type (CSV to VOTT JASON, for example), it seems to reset, ignoring all the previous tags you may have done.

Would there be a way to for the previous work to be held in a "reference" file format before it is exported. That way if we change between the export types it doesn't require us to start all over again?

I did it and had the same problem. Try tagging a single image and saving it simultaneously(ctrl+S).

Its a bit tedious but worked for me.
