title: Hugging Face model Bio_ClinicalBERT producing 404 error
body: <p>I'm building a Named Entity Recognition (NER) model using the Hugging Face implementation of emilyalsentzer/Bio_ClinicalBERT.  Up to today, I've had no issues with the model.  I'm hopeful that someone can help me understand why it's currently not working as expected.</p>
  <p>Question 1 - today, trying to train using:</p>
  <pre><code>MODEL_NAME = 'emilyalsentzer/Bio_ClinicalBERT'
  model = text.sequence_tagger('bilstm-bert', preproc, bert_model=MODEL_NAME)
  </code></pre>
  <p>results in this error:
  404 Client Error: Not Found for url: <a href="https://huggingface.co/emilyalsentzer/Bio_ClinicalBERT/resolve/main/tf_model.h5" rel="nofollow noreferrer">https://huggingface.co/emilyalsentzer/Bio_ClinicalBERT/resolve/main/tf_model.h5</a></p>
  <p>Does Hugging Face offer any kind of health check to ascertain the status of their models?</p>
  <p>Question 2 - working with files (model.h5, model.json, and preproc.sav) I'd saved from earlier training iterations, I'm getting the same 404 error shown above.  I don't understand wherein these files the call to Hugging Face is occurring.  It doesn't seem to be in the .json, and the .h5 and .sav file formats are hard to inspect.  Read more about what these files are:

  <p>Back in February, I'd used these exact model.h5, model.json, and preproc.sav files to run the NER app using Streamlit, no problem.  Not sure if this is temporary issue with Bio_ClinicalBERT or if I need to retool my original approach due to potentially permanent problems with this transformer model.</p>
