Hi

In my script I did some computationally costly processing of a large dataset and performed .save\_to\_disk on it. Unfortunately, it failed on that step, the dataset was not saved.

I still have the gigantic cache-4d6878f4ef3ef2f5.arrow file on the drive, am I able to load this cached version of dataset?

Regards

I found the answer:

```auto
Dataset.from_file

```
