title: Error : module 'geopandas' has no attribute 'read_file'
body: <p>I'm using for several weeks geopandas on Python.</p>
  <p>It worked well until yesterday, I believe until I reinstalled another package for geographic data.</p>
  <p>Now, I can still import geopandas, but when I execute :</p>
  <pre><code>my_data = gpd.read_file(path_data + &quot;my_data.geojson&quot;)
  </code></pre>
  <p>I get this error :</p>
  <pre><code>Traceback (most recent call last):
  
    File &quot;&lt;ipython-input-27-fb224ec85b60&gt;&quot;, line 1, in &lt;module&gt;
      my_data = gpd.read_file(path_data + &quot;my_data.geojson&quot;)
  
  AttributeError: module 'geopandas' has no attribute 'read_file'
  </code></pre>
  <p>I tried to uninstall geopandas (<code>pip uninstall geopandas</code>) and reinstall it (<code>conda install geopandas</code>), but it doesn't work better.</p>
  <p>Anyone knows what's happenning and what could I do ?</p>
  <p>Thank you very much !</p>
