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.

However, the notebook says it is Python3.
from platform import python_version
print(python_version())

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).

I work at AWS and my opinions are my own.
Was stuck in the same issue in Sagemaker notebook instance. Followed the guide here and resolved it by running:
%pip install matplotlib
Attaching the screenshot for your reference:
I am trying to deploy my Django project on a Bitnami server, but when I try to login through admin with my superuser i get the following error:

sudo chmod 664 /opt/bitnami/projects/django_project/db.sqlite3
sudo chown :www-data /opt/bitnami/projects/django_project/
sudo chmod 775 /opt/bitnami/projects/django_project/
Can you help me? :)
Bitnami developer here. You are setting the group to www-data. The Bitnami Apache user is "daemon".
Running the django tutorial for docker compose, but the command to init the django project is not working as expected.
$ docker-compose run web django-admin.py startproject composeexample .

Please pass the -d flag when using `docker-compose run`.
In windows "interactive" mode is not supported so I modified the command to run in "detached" mode.

This seems to create the boxes.. but my current directory shows no new files (from the django-admin command).
$ ls

How do I get the container output to sync with the current working directory as expected?
The fix was to uninstall Windows 10 and install a *nix system. The files then appear as per the tutorial.

I have three directories(farmio,farmio-table,farmio-table-throttle) in apps directory of AWS-Centos server under username ec2-user, every time I do a ls -la I see two folders(farmio-table,farmio-table-throttle) accessed frequently and the pid file stored inside the folder are wiped out for which my java programs doesn't execute properly.

Every time I try to check the folders are changed or replaced after five minutes.
Is there any way I could know which user and which command is executed in this directory so that its files are replaced/modified in Centos.
Use command history to check all the previously run commands.

This is fossil version 1.23 [957b17af58] 2012-08-08 11:25:57 UTC
But 1.24 fails, with 'No such file' even though a ls command shows the file is present, like this:

Richard Hipp rebuilt the 1.24 linux binary. The new version works fine.
