About Lab!

Semester Outline

Policies

• Labs this semester are hybrid. You are free to complete the lab yourself on DataHub using your own computer.
• You do not need to attend the full lab section. However, you must come to Cory 111 during your assigned lab section before it ends to get checked off.
• To receive credit, you must pass all autograder checks and then get checked off by a lab TA/UCS1 during your assigned lab section.

​

Policies

• In a checkoff, you will demonstrate your work from portions of the lab and answer conceptual questions related to the lab. You should aim to get checked off by the end of your lab section.
• If (and only if) you attend the lab in person, you may work with a partner and get checked off together. If working async, you can collaborate but you will need to show a completed autograder on your notebook.

​

Lab Grade

Buffer Labs

• During buffer lab weeks, you may get checked off for only one missed lab that occurred since the previous buffer week.
• No other labs can be checked off.
• The eligible labs for makeup for each buffer lab period will be released in a timely manner. Please look out on Ed for each buffer lab signup.

Important Notes

• No food or drink is allowed in the lab room! Please eat outside of the lab room.
• When you are done with the lab:
• Clean up your workspace
• If using the lab computers:
• Log out of your account
• Turn off the display
• Do not turn off the desktop
• If you need any accommodations, please email eecs16a.lab@berkeley.edu

Bootcamp Time!

Marimo Notebook

A web-based interactive computational environment similar to Jupyter Notebook

• Document containing a list of input/output cells
• Can contain code, text, mathematics, plots and rich media
• .py file extension
• But what does this look like?

Marimo Notebook

• Stateless list of input & output
• The order you run these cells does not matter!
• Control/Command + Enter to run current block
• Shift + Enter to run and move forward

Marimo Notebook

• Running / changing one cell executes downstream cells
• If I change variable v, the next two cells are automatically affected

Marimo Notebook

• Variable names for assignment can only happen in one cell.
• You cannot define a variable in one cell and redefine it in another cell

Marimo Notebook

• Text/Markdown
• Expand on the cell (simply click inside)
• Control/Command + Enter to format current block
• Shift + Enter to format current block and move forward

Running the Marimo Lab

• If you are using the lab computer, login using your CalNet ID
• Click on the Datahub link from the course website
• You should see a .py file to start working on the lab!

Using the Lab Computers

• Log in to the computers using your Calnet ID

Python Bootcamp

• Review Python
• List comprehension
• Introduction to NumPy - scientific computing in Python
• NumPy functions: np.linspace, np.eye, np.transpose, np.linalg.inv, np.dot
• NumPy objects: arrays, matrices
• NumPy array slicing, array reshaping
• All the tools you will need for future labs

Python Guide

• Introduction to Python!
• Link in the Lab Notebook (and on the course website)
• Contains fundamental Python concepts and tools that you will need for all EECS 16A Labs
• Not a requirement, but a resource!

Checking-off Today

• Work on Python Bootcamp
• Pass all autograder checks
• Follow the directions linked at bottom of the lab
• Fill out Google form
• During checkoff:
• Introduce yourself: name, major, year, hobbies
• Open the Python Bootcamp
• Show the final autograder check result
• Find this presentation on the website
• If you want to add songs to our playlist: tinyurl.com/16a-playlist
