The values of [email protected] and tflite size seem to be empty for Experiment03. Are you planning to update it?

Sure. I update it just now.

For Experiment02, where could I find the configuration and tflite files?

Here are the tflite files. cfg files are placed on config/training folder.

Thanks, could you also release the corresponding frozen .pb files too? I wanted to compare them with my trained model.

I just have saved_model now. If you open new issue for this, I’ll share soon. Thank you.

Experiment04

• various stage number of CPM models
• input shape: [1,192,192,3]
• output shape: [1,24,24,14]

Hyperparameters

• number_of_epoch: 200 (about 140.2k step) → need to experiment with bigger epoch in the production model

The first [email protected] doesn't satisfy. I'll reconstruct and experiment again.
