Lean 4 tactic prediction examples extracted from Mathlib. 

These examples have **not** been formatted for instruction tuning (including data splits).

Please see `l3lab/ntp-lean-mathlib-instruct-*` for datasets with instruction tuning examples.


### Version
Generated using `ntptutorial`'s `ntp-training-data` with the following config:

```json
{
    "repo": "https://github.com/leanprover-community/mathlib4",
    "commit": "cf8e23a62939ed7cc530fbb68e83539730f32f86",
    "lean": "leanprover/lean4:v4.4.0",
    "name": "mathlib",
    "import_file": "Mathlib.lean",
    "imports": ["Mathlib"]
}
```

### Example usage:

```bash
ds = datasets.load_dataset('wellecks/ntp-lean-mathlib-tactic')

print(len(ds['train']))
# ==> 337162
```

### Format:
