When the optional ``huggingface_hub`` package is installed, all models
|
| 92 |
-
automatically gain the ability to be pushed to and loaded from the
|
| 93 |
-
Hugging Face Hub. Install with::
|
| 94 |
-
|
| 95 |
-
pip install braindecode[hub]
|
| 96 |
-
|
| 97 |
-
**Pushing a model to the Hub:**
|
| 98 |
-
|
| 99 |
-
.. code::
|
| 100 |
-
from braindecode.models import BDTCN
|
| 101 |
-
|
| 102 |
-
# Train your model
|

|
| 104 |
-
# ... training code ...

-
**Loading a model from the Hub:**
|
| 113 |

-
.. code::
|
| 115 |
-
from braindecode.models import BDTCN
