Problems loading mnist in tensorflow on Mac OS

Please help, I encountered the following errors while attempting to download the MNIST dataset with Tensorflow.

Using TensorFlow backend.

I installed the latest version of Pip and the issue was fixed

Update using the following command: "pip install --upgrade pip"

TensorFlow 2 packages require a pip version >19.0.

I suggest you install TensorFlow in a separate virtualenv.

Follow the following steps here: Installing TensorFlow with virtualenv

And always remember to activate the virtualenv environment each time you use TensorFlow in a new shell by running:
$ source ~/<target_directory>/bin/activate
