<h2>Update 2019-08</h2>

<p>Now you can use Embedding Projector easily in Colab with PyTorch's SummaryWriter</p>

<pre class="lang-py prettyprint-override"><code>import numpy as np
import tensorflow as tf
import tensorboard as tb
tf.io.gfile = tb.compat.tensorflow_stub.io.gfile
from torch.utils.tensorboard import SummaryWriter

vectors = np.array([[0,0,1], [0,1,0], [1,0,0], [1,1,1]])
metadata = ['001', '010', '100', '111']  # labels
writer = SummaryWriter()
writer.add_embedding(vectors, metadata)
writer.close()
%load_ext tensorboard
%tensorboard --logdir=runs
</code></pre>

<h2>Update 2020-02</h2>

<p>The %tensorboard magic now works properly again.</p>
How to use tensorboard Embedding Projector?
<p>How do I use the Embedding Projector included in Tensorboard?</p>

<p>I can't find any documentation for it. There are some references to it <a href="https://www.tensorflow.org/versions/master/how_tos/embedding_viz/index.html" rel="noreferrer">here</a>, but there's no step-by-step example/tutorial on how to use it.</p>
