Seeking Guidance on Reproducing Reported Accuracy

I am currently working on reproducing the reported accuracy of Protonet on miniImageNet with a 1-shot scenario (63.17% -> 66.63%). I initially trained the classifier-baseline using the provided code and attempted to train ProtoDiff.

However, I encountered challenges as the accuracy scores were not as expected. Specifically, after training both the classifier-baseline and ProtoDiff on convnet4 and resnet12, the accuracy scores were suboptimal (resnet12: 63.25% -> 62.88%, convnet4: 41.61% -> 31.52%).

Do you have plans to release the final code?

I would appreciate any guidance or insights you can provide on the configurations I used. Please find the details below:
