 ## Fine-tune
 
+### Requirements
+
 If you want to fine tune this operator, make sure your timm version is 0.4.12, and the higher version would cause model collapse during training.
+```python
+! python -m pip install tqdm augly timm==0.4.12 pytorch-metric-learning==0.9.99
+```
+
 
 ### Get start to fine-tune
 Just call method op.train() and pass in your args.
