Amazon Web Services – Removing and then reinstalling Anaconda on an AWS Ubuntu Deep Learning EC2 instance and unable to enter in-depth learning environments

I just set up an Ubuntu Deep Learning AMI EC2 instance. I am a beginner on AWS / Packet Processing.

My goal is to use the instance to run a Python deep learning script. This script uses a variety of packages.

When installing some of these packages with conda, an error has occurred indicating inconsistencies in the environment for more than 100 packages. After several attempts to solve this problem, I thought that removing Anaconda and reinstalling it could do the trick. After that, I realized that I had perhaps further spoiled my instance. I can no longer use the predefined deep learning environments for which the AMI has been configured because they have been accessed using conda commands, which seems to have been removed (IMO).

I've tried repeating the commands, but I get an error stating that these environments no longer exist. A tutorial using these commands is mentioned here:
https://docs.aws.amazon.com/dlami/latest/devguide/tutorial-conda.html

active source tensorflow_p36

I was expecting the above to enter the tensorflow_p36 environment. A sin:

(tensorflow_p36) ubuntu @ ip-172-31-45-96: ~ / scripts

However, this gives an error message:

impossible to find the environment: tensorflow_p36

I realize that the uninstallation of conda was a major rookie error that seems to have totally disabled my instance. If anyone has any ideas to get it back, it would be very appreciated!

thank you so much
