+# FineTune BERT with Stanford Sentiment Tree Bank
+- reference [repo](https://github.com/kabirahuja2431/FineTuneBERT)
+
+## Requirements
+- python 3.9
+- mindspore 2.3.1
+- mindnlp 0.4.1
+- pandas
+
+## Data
+Download the data from this [link](https://gluebenchmark.com/tasks). There will be a main zip file download option at the right side of the page. Extract the contents of the zip file and place them in data/SST-2/
+
+## Args for training the model
+To train the model with fixed weights of BERT layers, set:
+```
+args.freeze_bert = True 
+```
+To train the entire model i.e. both BERT layers and the classification layer, set:
+```
+args.freeze_bert = False 
+```
+
+other optional arguments:
+- args.device_target : Ascend
+- args.device_id 
+- args.base_model_name_or_path : 'bert-base-uncased' or the path to the model
+- args.dataset_name_or_path : path to the data directory
+- args.maxlen : maximum length of the input sequence
+- args.batch_size : batch size
+- args.lr : learning rate
+- args.print_every : print the loss and accuracy after these many iterations
+- args.max_eps : maximum number of epochs
+- args.save_path : path to save the model, if not provided the model will not be saved, such as './outputs/'
