Training atari_userhint_v2

[HanzVivatma]

Thank you for sharing such a great model.

I am about to train atari_userhint_v2 model from scratch but being confused with dataset. Following the instruction, there is need of 3 types of datasets. I dont know how to obtain 2 types of datasets below:

• SKETCH_PATH: The name of the directory that contains line arts obtained by SketchKeras
• SS_PATH: The name of the directory that contains quantized color images obtained by superpixel

Could you please share a model to get sketch and ss dataset as well as give me a detail of instruction for training model from scratch?

I will be grateful for your assistance.

Thank you for the issue, and I am sorry for insufficient instructions.

• When it comes to SS_PATH, you do not have to care about that because the path is not actually used in the code. So, you can set any kind of path as SS_PATH. I recommend that you can set the same path as SKETCH_PATH or DATA_PATH.
• As for SKETCH_PATH, the path contains line arts corresponding to the images in DATA_PATH, and the line arts are obtained by running SketchKeras. You can use the scripts in the repository and modify aligning with your purpose.

Sorry for the late reply.

The dataset I mainly used for training is this. If you share the result, it might give me more ideas about the suitable comments.

Sorry for the late response.

I would like to know whether the model is overfitting or not. Could you check the colorized result of training dataset? If the result is appropriate, I think that the model is overfitting. In that case, you might have to increase the number of dataset. If not, I would like to know the modifications that you made in the code to run the script (e.g. hyperparameter settings in param.yaml).

Thanks for your valuable assistance.

Currently, I would like to train model for Flatten hints (colorization based on scribble hints in GUI application). Could you please suggest that what type of model I should train: atari_diverse, atari_spade, atari_userhint or atari_whitebox?

I am looking forward to your reply

Sorry for the late response. I think that atari_whitebox is the reasonable choice. atari_userhint is the straightforward way to utilize scribble hints, but the code would not be fully organized.
