I am trying to make progress on Lesson 3 of the Advanced Tello Programming modules. When I “Run” the code in the **Tello\_Setup\_Test\_Notebook** , I am not getting the correct response from Jupyter Notebook. I either get **NameError: ‘Tello’ is not defined** (see below). Or when I tried on another computer the Tello\_Setup\_Test\_Notebook indicated **ModuleNotFoundError: NO module named 'djiTellopy** ’. Any suggestions?

Scroll down to the README on this page:

[dbaldwin/tello-adv-setup: Advanced Tello Programming with Python 3 and OpenCV from Pat Ryan (github.com)](https://github.com/dbaldwin/tello-adv-setup)

Did you follow this step:

To install the DJITelloPy API package, in the terminal window type the following:

`pip install https://github.com/damiafuentes/DJITelloPy/archive/master.zip`

When the pip command completes let us check that the install worked.

In the terminal window type the following:

`python`

and then

`from djitellopy import Tello`

I tried to follow your instructions above on 2 of my computers. I succeed on one and not on the other. So…on the successful computer I took the next step in Lesson 3 and my results are indicated below:

What did I do wrong? How do I proceed.  
Thank you for your consideration.
