title: Symbolic link (ln) operation not supported Colab
body: <p>During a model training, I got this error:</p>

  <p>First I thought it was maybe a problem with my path, but it wasn't, and I discovered that a colab session does not support the symbolic link (ln) operation, for most of the ways you could run it (also with os.system):</p>

  <p>My question is: Are there any other ways that I did not explore? or did someone get the same error with Colab? (not specifically with <strong>ln</strong>, but any other not supported operation)</p>
