  <p>but when I try to import it in an environment I fail. The terminal gives the following message : </p>
  
  <blockquote>
    <p>Solving environment: failed. </p>
  </blockquote>
  
  <p>I used the command</p>
  
  <pre class="lang-bash prettyprint-override"><code>conda env update -f My-environment.yml
  </code></pre>
