Using user data, your should install your dependencies this way :

python3 -m venv /home/ec2-user/vertual-Environment
/home/ec2-user/vertual-Environment/bin/pip install django
/home/ec2-user/vertual-Environment/bin/pip install djangorestframework
/home/ec2-user/vertual-Environment/bin/pip install pillow

When using userdata, your script are executed independently, regardless of what have been done in previous executions.

You have to source your python env envrionment.

Example (I have verified now the code on Amazon Linux 2):

#!/usr/bin/env bash
sudo yum update -y
sudo yum install python3 python3-pip -y
sudo pip3 install --upgrade pip 
pip install --upgrade pip
python3 -m venv /home/ec2-user/vertual-Environment

# source your new python env
source /home/ec2-user/vertual-Environment/bin/activate

pip install django
pip install djangorestframework
pip install pillow
