checkpoints don't seem to be working

[eniompw]

I'm testing out train.py on google colab but no checkpoints are created, even after iter 1000 .

I'm using this command:

!cd /content/nanoGPT/ && python train.py --dataset=shakespeare --compile=False --n_layer=4 --n_head=4 --n_embd=64 --eval_iters=20 --block_size=64 --batch_size=8 --init_from=gpt2 --always_save_checkpoint=True --dtype=float32
