Import the <code class="docutils literal notranslate"><span class="pre">datasets</span></code> and <code class="docutils literal notranslate"><span class="pre">transforms</span></code> to load and transform computer vision datasets. Import <code class="docutils literal notranslate"><span class="pre">matplotlib</span></code> for drawing, and <code class="docutils literal notranslate"><span class="pre">time</span></code> for benchmarking.

| <p>Apache MXNet is an effort undergoing incubation at The Apache Software Foundation (ASF), <span style="font-weight:bold">sponsored by the <i>Apache Incubator</i></span>. Incubation is required |
| of all newly accepted projects until a further review indicates that the infrastructure, |
| communications, and decision making process have stabilized in a manner consistent with other |
| successful ASF projects. While incubation status is not necessarily a reflection of the completeness |
| or stability of the code, it does indicate that the project has yet to be fully endorsed by the ASF. |
