title: sns scatterplot don't show but no error si thrown
body: <p>I am trying to visualize the high dimensions of features using tsne. When plotting nothing shows up but no error is thrown.</p>
  <pre><code>import numpy as np

  df = pd.read_pickle(&quot;features/twitterxlmrobertabase_text_embed_w_dum_data.p&quot;)
  
  df_topic = pd.read_pickle(&quot;data/db_hbm/prepared_data_w_dum_data.p&quot;)

      data[&quot;topic&quot;] = label_keys[df_topic[i][&quot;topic&quot;][0]]
      i += 1

  x_embedded = tsne.fit_transform(np.array(df_emb[&quot;embedding&quot;].tolist()))
  
  labels = df_emb[&quot;topic&quot;].values
  
  plt.figure(figsize=(6, 5))
  plt.title(&quot;title&quot;)

  # plt.legend()
  plt.show()
  </code></pre>
  <p>The dataframe I am using has two columns &quot;embedding&quot; and &quot;topic&quot;. the first column is of type &lt;class 'numpy.ndarray'&gt;. the second column of type int. The values that come from the data frame are visualized <a href="https://i.stack.imgur.com/zTeMO.png" rel="nofollow noreferrer">here</a>. I think the problem come from the structure of the first column(array of array) that why the plot is not able to map each element to its corresponding topic. For more clarification this is how the <code>df_emb</code> looks <a href="https://i.stack.imgur.com/FmfHu.png" rel="nofollow noreferrer">looks like</a>
  Can anyone help?</p>
