  <p>I have seen that in my Anaconda environment, I use <code>python 3.6.13</code>, while in Google Colab is present <code>python 3.7.10</code>. Could it be that the problem? I tried to downgrade the python version in Google Colab, but I was not able to downgrade it. Could anyone help me, please?</p>
