title: module 'dask' has no attribute 'read_fwf'
body: <p>I want to use dask.read_fwf(file), but I get there error</p>
  
  <pre><code>AttributeError: module 'dask' has no attribute 'read_fwf'
  </code></pre>
  
  <p>The same problem occurs for read_csv and read_table.</p>
  
  <p>I have uninstalled and reinstalled dask, as well as trying to rename my 'csv.py' file in \dask\dataframe\io. The same problem occurs after both of these attempted fixes.</p>
  
  <p>pd.read_fwf and the like work fine.</p>
