can't access my finetuned model

[GP24CairoUni]

from ragatouille import RAGTrainer

trainer = RAGTrainer(model_name="MyFineTunedColBERT",
pretrained_model_name="colbert-ir/colbertv2.0")

trainer.prepare_training_data(raw_data=positive_pairs,
data_out_path="./data2/",
all_documents=cleaned_documents,
mine_hard_negatives=True)

training_path = trainer.train(batch_size=16,
nbits=4,
maxsteps=500000,
use_ib_negatives=True,
dim=128,
learning_rate=5e-6,
doc_maxlen=256,
use_relu=False,
warmup_steps="auto")

I finished finetuning but I cant access and use the model again and no checkpoints on my local storage
