Training and evaluation data

This model was trained/evaluated on "test+validation" data from google/fleurs google/fluers - HuggingFace Datasets.

Training procedure

The training was done in Lambda Cloud GPU on A100/40GB GPUs, which were provided by OpenAI Community Events Whisper Fine Tuning Event - Dec 2022. The training was done using HuggingFace Community Events - Whisper - run_speech_recognition_seq2seq_streaming.py using the included whisper_python_am_et.ipynb to setup the Lambda Cloud GPU/Colab environment. For Colab, you must reduce the train batch size to the recommended amount mentioned at , as the T4 GPUs have 16GB of memory Whisper Fine Tuning Event - Dec 2022. The notebook sets up the environment, logs into your huggingface account, and generates a bash script. The bash script generated in the IPYNB, run.sh was run from the terminal to train bash run.sh, as described on the Whisper community events GITHUB page.

Training hyperparameters

The following hyperparameters were used during training:

learning_rate: 1e-05
train_batch_size: 64
eval_batch_size: 32
seed: 42
gradient_accumulation_steps: 2
total_train_batch_size: 64
optimizer: Adam with betas=(0.9,0.999) and epsilon=1e-08
lr_scheduler_type: linear
lr_scheduler_warmup_steps: 500
training_steps: 5000
mixed_precision_training: Native AMP
do_eval=False

Recommendations

Limit training duration for smaller datasets to ~ 2000 to 3000 steps to avoid overfitting. 5000 steps using the HuggingFace - Whisper Small takes ~ 5hrs on A100 GPUs. Encountered RuntimeError: The size of tensor a (504) must match the size of tensor b (448) at non-singleton dimension 1 which is related to Trainer RuntimeError as some languages datasets have input lengths that have non-standard lengths. The link did not resolve my issue, and appears elsewhere too Training languagemodel – RuntimeError the expanded size of the tensor (100) must match the existing size (64) at non singleton dimension 1. To circumvent this issue, run.sh only trains and save the model. Then run python run_eval_whisper_streaming.py --model_id="openai/whisper-small" --dataset="google/fleurs" --config="am_et" --device=0 --language="am" to find the WER score. Erroring out during evaluation prevents the trained model from loading to HugginFace.
