| # Pickle to skops converter | |
| This space converts your pickle files to skops format. You can read more on the | |
| skops format [here]( https://skops.readthedocs.io/en/stable/persistence.html). | |
| You can use `skops.io.dump(joblib.load(in_file), out_file)` to do the | |
| conversion yourself, where `in_file` is your source pickle file and `out_file` | |
| is where you want to save the skops file. But only do that **if you trust the | |
| source of the pickle file**. | |
| You can then use `skops.io.load(skops_file, trusted=unknown_types)` to load the | |
| file, where `skops_file` is the converted skops format file, and the | |
| `unknown_types` is what you see in the "Unknown Types" box bellow. You can also | |
| locally reproduce this list using | |
| `skops.io.get_untrusted_types(file=skops_file)`. You should only load a `skops` | |
| file that you trust all the types included in the `unknown_types` list. | |
| ## Requirements | |
| This space assumes you have used the latest `joblib` and `scikit-learn` | |
| versions installed on your environment to create the pickle file. | |
| ## Reporting issues | |
| If you encounter an issue, please open an issue on the project's repository | |
| on the [issue tracker]( | |
| https://github.com/skops-dev/skops/issues/new?title=CONVERSION+error+from+hf.space&body=Paste+the+error+message+and+a+link+to+your+pickle+file+here+please) | |
