My Anaconda don't want none :(

Hi all! New user here having trouble with the installation.
I’m in Anaconda, working on step 6 of my TF installation, but there appears to be a problem somewhere before step 6 bc after entering python3 -c "import tensorflow as tf; print(tf.reduce_sum(tf.random.normal([1000, 1000])))" I’m getting the following error:

(tf) C:\Users\Mathi>python3 -c "import tensorflow as tf; print(tf.reduce_sum(tf.random.normal([1000, 1000])))"
Traceback (most recent call last):
  File "<string>", line 1, in <module>
ModuleNotFoundError: No module named 'tensorflow'

I’m pretty darn sure that I spent all flippin’ day installing it, so I’m a bit distressed. Any help would be greatly appreciated!

(tf) C:\Users\Mathi>python3 -c "import tensorflow as tf; print(tf.reduce_sum(tf.random.normal([1000, 1000])))"
Traceback (most recent call last):
  File "<string>", line 1, in <module>
ModuleNotFoundError: No module named 'tensorflow'

Above error may be due to, If you have multiple python versions installed on your machine, you might have installed the tensorflow package using the incorrect version or your IDE might be set up to use a different version.

Have you tried to install using Miniconda? Because Miniconda is the recommended approach for installing TensorFlow with GPU support. Thank you!
