body: <p>I'm trying to learn how to <a href="https://cython.readthedocs.io/en/latest/src/tutorial/embedding.html" rel="nofollow noreferrer">Embedd Cython modules in c Applications</a> from the Cython Website, I have Literally copy pasted the entire example and it doesn't work. it gives me a <code>struct &quot;_typeobject&quot; has no field &quot;tp_name&quot;</code> Error every time, I am new to all this and I'm hoping someone could explain what I'm missing.</p>
  <p>I don't know if it is relevant but I'm using a setup.py file to feed in my arguments</p>
