SageMaker Studio Image - pip not found and no python 3 in terminal for Python 3 notebook instance

Question

Launched Data Science Python 3 instance in the SageMaker Studio.

Launched a terminal from the Notebook menu "Launch terminal in current SageMaker image".

Tried to run pip but it says not found. Do I need to install pip by myself?

root@datascience-1-0-ml-t3-medium-1abf3407f667f989be9d86559395:~/# pip
bash: pip: command not found

Alto there is no Python3 available apparently from within the terminal.

root@datascience-1-0-ml-t3-medium-1abf3407f667f989be9d86559395:~# python3 
bash: python3: command not found

root@datascience-1-0-ml-t3-medium-1abf3407f667f989be9d86559395:~# python --version
Python 2.7.16

root@datascience-1-0-ml-t3-medium-1abf3407f667f989be9d86559395:/usr/bin# ls -lrt | grep python

lrwxrwxrwx 1 root root        23 Oct 10  2019 pdb2.7 -> ../lib/python2.7/pdb.py

However, the notebook says it is Python3.

from platform import python_version
print(python_version())
---
3.7.10

And can run pip in the cell.

Appreciate any explanation what is going on.

SageMaker Studio image terminals use conda for package management. The data science notebook uses the base environment. You can use pip once you switch to base (also note that the python version is 3.7).

root@datascience-1-0-ml-t3-medium-xx:~# conda env list
# conda environments:
#
base                  *  /opt/conda

root@datascience-1-0-ml-t3-medium-xx:~# conda activate base

(base) root@datascience-1-0-ml-t3-medium-xx:~# pip show pip
