hey guys, It seems that eval loss is not being logged onto wandb ([No loss being logged, when running MLM script (Colab) - #3 by Neel-Gupta](/static-proxy?url=https%3A%2F%2Fdiscuss.huggingface.co%2Ft%2Fno-loss-being-logged-when-running-mlm-script-colab%2F8134%2F3))

And it looks like when the code cell for pre-training has run, it just keeps running even after the model has been trained.  
That is, it apparently never executes next to `wandb.finish()` and keeps on going.

Any ideas on how I can solve these issues?
