Adding a new dataset

[andreadaou]

Hi !

As mentioned in README.md to add a custom dataset:

• Create a new entry in dataset_config.py, add the folder with the data in path and any other transformations or class ordering needed.
• The option from line 135 in data_loader.py should be enough.
• In the same folder as the data add a train.txt and a test.txt files.

If I follow the steps mentioned above to add newdataset, I will get:

Till now, is this correct?

In the newdataset folder added in data folder shown in FACIL capture, should I insert all the train and test images as .jpg files? In addition to train.txt and test.txt ?

Sorry for this long question but I'm having a problem when adding a custom dataset. Appreciate your help !! Thank you :)

If you are using our system of train.txt and test.txt files. Then you do not need lines 136 and 137 (from the third image you posted). It should work directly with the part from 139-145. With the else-branch you have created the dataset is probably empty, and that's why it would not be working.

The .txt. files will contain as the first column the path to the images, so it doesn't matter where the images are stored as long as the paths are correct. I would recommend using absolute paths.

The dataset_config looks correct.

Usually, the data folder is created inside the FACIL folder, same "height" in the tree as src or scripts. So that could be an issue too?

Feel free to post the errors you get so I know where they might be coming from.

Thank you so much @mmasana !! I believe the code is now operating correctly.

I will post the new errors if any occur (hopefully none will). Thank you again !
