title: Module Not Found Error when importing Pytorch_Transformers
body: <p>After downloading pytorch_transformers through Anaconda and executing the import command through the Jupyter Notebook, I am facing several errors related to missing modules. </p>
  
  <p>I tried searching sacremoses to import the package via Anaconda, but it is only available for Linux machines. Has anyone else faced similar issues? Thanks in advance!</p>
  
  <p><code>from pytorch_transformers import BertTokenizer, BertModel, BertForMaskedLM</code></p>
  
  <p>This is the error:</p>
