Data Science: with pandas, NumPy, PyTorch and more

Data Science refresher with pandas and NumPy for community learning. This tutorial uses the fundamentals of Python language as such and does not emphasise on teaching them primarily.

Install Python and pip

• Install Python using GUI installer wizard or with the following command: apt install python3

• Install pip with the command: apt install python3-pip

Install and enable virtualenv

pip install virtualenv virtualenv dspandas

Activate the virtual environment

• Activate virtualenv in *nix systems as: src ./dspandas/bin/activate

• Activate virtualenv in Windows box as: dspandas\scripts\activate`

Launch Jupyter Notebook

• Start Notebook with the command: jupyter notebook
• Exit the Notebook with the menu option: ´File >> Shut down´

Select the virtual environment to run Jupyter Notebook in

Be default, the Python kernel of the virtual environment is not listed in Jupyter to choose out of the available kernel options. Enable the listing of your new virtual env kernel with the commands:

• Install ipykernel only if it is not installed- ´pip install ipykernel´

• Enable the kernel- ´python -m ipykernel install --user --name=dspandas´
• Optionally you may check the effect without launching Notebook with the command-

jupyter kernelspec list

• Again launch Notebook with the command: jupyter notebook

• Select venv kernel for Notebook

Install pandas to start with calculations and transformations
