Hey folks!First off huge thanks to@patrickvonplatenand@valhallafor putting this challenge together, really excited to do some Irish language training!I’m also really happy to say that the team here at Weights & Biases would like to support the community with their training as much as we can!(If you haven’t used Weights & Biases before you can findbrand new docs for our Hugging Face integration hereor check out the XLSR colab linked below)Quick SummaryWeights & Biases will create public language-specific W&B Projects so that multiple people can collaborate effectively on the same language,add your language hereWe have abeta dataset visualisationfeature that I think is suuper useful to explore speech datasetsWe have aW&B XLSR Colabto show off how best to instrument your code to log your models training progress as well as upload and version your datasets, tokenizers, processors and models (before logging your best model to the HF Model Hub).Language-specific W&B Projects - just askIn order to help organise multiple people working on the same language, we are happy to createpublic language-specific W&B Projectsthat anyone will be able to log their results, datasets, models, tokenizers etc to. This way folks working on the same language can work as a team and can easily share results and see the configs and hyperparameters that were used for specific model runs.Go here to add the language-specific project you’d like us to requestW&B Dataset Visualisation [Beta]I’m suuuper excited about using this feature to quickly explore speech datasetsWith this new W&B feature (still in Beta) you can easily explore rich media tables to better understand your speech dataset. I’ve made aquick video demowhich I think will best explain the value of this feature for EDA of rich media such as audio and video.To see the code that created this rich media table in W&B Artifacts, see theW&B XLSR ColabThis is still in beta and the team would love to hear any feedback you have on it, please feel free to ping me about it and I can pass it on to the teamDocs are herefor more info.W&B XLSR ColabWe have also created aW&B XLSR Colabwith setup and training from top to bottom to show how you can get the most out of Weights & Biases. Getwandbsetup to log your models training as well as version your datasets, tokenizers, processors and models!To make finding relevantwandbcode a bit easier, the relevant headings in the notebook start with “WANDB: …” Just search “wandb”  to jump through and find the wandb code you’re looking for!Let us know how it goes!Let use know how integrating and using W&B goes and whether you have any issues! I’ll be active here and in the Hugging Face XLSR slack channel to answer any Weights & Biases questions you might have!@boriswill also be able to help out too!Best of luck with the challenge everyone!!

FYI I just fixed a permissions issue with the Weights & Biases projects created so farif anyone had trouble logging to a project already created please try again, it should be working nowCheck out the post above for more info on W&B Projects and feel free to drop a post here or DM me directly with any questions you have

Using W&B with the OVHrun_common_voice.pyscriptRun the following in the terminal# 1. Make sure you have the latest W&B and Transformers from master
pip install git+https://github.com/huggingface/transformers.git
pip install wandb --upgrade

# 2. login to wandb
wandb login

# 3. Set your Project name and Entity (no quotes needed around `wandb` for example) 
export WANDB_ENTITY = wandb
export WANDB_PROJECT = xlsr-french

# 4.  Save your model to W&B (optional)
export WANDB_LOG_MODEL = trueNow you just have to add  the usual wandb parameters that Trainer needs to thefinetune.shscript:python /workspace/wav2vec/run_common_voice.py \
    --report_to="wandb"
    --run_name = 'fr-baseline',   # Name your run, optional
    --load_best_model_at_end = True, 
    --metric_for_best_model='wer',  
    --greater_is_better=False,
    .....

    loudness = meter.integrated_loudness(sa)

    # loudness normalize audio to -12 dB LUFS
    loudness_normalized_audio = pyln.normalize.loudness(sa, loudness, -12.0)

    return loudness_normalized_audiodef speech_file_to_array_loud_norm_fn(batch):
