<p>Say, you try to import <code>label_map_util</code> from the <code>utils</code> module when running TensorFlow’s <code>object_detection</code> API. You get the following error message:</p>
<pre class="EnlighterJSRAW" data-enlighter-language="python" data-enlighter-theme="" data-enlighter-highlight="1,5" data-enlighter-linenumbers="" data-enlighter-lineoffset="" data-enlighter-title="" data-enlighter-group="">>>> from utils import label_map_util

<h2>Solution Idea 1: Fix the Import Statement</h2>
<p>The most common source of the error is that you use the expression <code>from utils import <something></code> but Python doesn’t find the utils module. You can fix this by replacing the import statement with the corrected <code>from object_detection.utils import <something></code>. </p>
<p>For example, do not use these import statements:</p>
<pre class="wp-block-preformatted"><code>from <strong>utils</strong> import label_map_util
from <strong>utils</strong> import visualization_utils as vis_util</code></pre>
<p>Instead, use these import statements:</p>
<pre class="wp-block-preformatted"><code>from <strong>object_detection.utils</strong> import label_map_util
from <strong>object_detection.utils</strong> import visualization_utils as vis_util</code></pre>
<p>Everything remains the same except the <strong>bolded</strong> text. </p>
<p>This, of course, assumes that Python can resolve the <code>object_detection</code> API. You can follow the <a rel="noreferrer noopener" href="https://tensorflow-object-detection-api-tutorial.readthedocs.io/en/latest/" data-type="URL" data-id="https://tensorflow-object-detection-api-tutorial.readthedocs.io/en/latest/" target="_blank">installation recommendations here</a>, or if you already have TensorFlow installed, check out the Object Detection API installation tips <a rel="noreferrer noopener" href="https://tensorflow-object-detection-api-tutorial.readthedocs.io/en/latest/install.html#install-the-object-detection-api" data-type="URL" data-id="https://tensorflow-object-detection-api-tutorial.readthedocs.io/en/latest/install.html#install-the-object-detection-api" target="_blank">here</a>.</p>
<h2>Solution Idea 2: Modify System Path</h2>
<p>Another idea to solve this issue is to append the path of the <strong><em>TensorFlow Object Detection API</em></strong> folder to the system paths so your script can find it easily. </p>
<p>To do this, import the <code>sys</code> library and run <code>sys.path.append(my_path)</code> on the path to the <code>object_detection</code> folder that may reside in <code>/home/.../tensorflow/models/research/object_detection</code>, depending on your environment.</p>
<pre class="EnlighterJSRAW" data-enlighter-language="python" data-enlighter-theme="" data-enlighter-highlight="" data-enlighter-linenumbers="" data-enlighter-lineoffset="" data-enlighter-title="" data-enlighter-group="">import sys
sys.path.append('path/to/object/detection/folder')</pre>
<h2>Solution Idea 3: Dirty Copy and Paste</h2>
<p>I don’t recommend using this approach but I still want to share it with you for comprehensibility. Try copying the <code>utils</code> folder from <code>models/research/object_detection</code> in the same directory as the Python file requiring <code>utils</code>.</p>
<h2>Solution Idea 4: Import Module from Another Folder (Utils)</h2>
<p>This is a better variant of the previous approach: use our in-depth guide to figure out a way to import the utils module correctly, even though it may reside on another path. This should usually do the trick.</p>
