training from scratch, loss decreased very slow

[chrisx599]

have anyone who training from scratch, not use pre-trained weight of ViT-B?
Can author or anyone released the training log of train from scratch？
the author said it takes more epochs to training from scratch, but did'nt released a concrete number, can author says this number?
when i trained 15 epochs, the accuracy is only 16%, and from the beginning, it's just 4%, i'm so confused is that normal?
