Hi, I don’t know how to get around an error code on a step in the course: Tello Camera Control with DroneBlocks Python App.
I followed along OK until the 3rd section "Download and Run the DroneBlocks Python Code (5:16) following the windows installation instruction video @ https://learn.droneblocks.io/courses/708045/lectures/12773328
When I attempt to run app.py for the first time it fails to get flask up and running with errors shown below.
Can you help please?
** On entry to DGEBAL parameter number 3 had an illegal value ** On entry to DGEHRD parameter number 2 had an illegal value ** On entry to DORGHR DORGQR parameter number 2 had an illegal value ** On entry to DHSEQR parameter number 4 had an illegal value ImportError: numpy.core.multiarray failed to import Traceback (most recent call last):

Here is a ‘pip list’ showing I had successfully loaded packages/dependencies up to that point:

You should consider upgrading via the ‘c:\users***\appdata\local\programs\python\python37\python.exe -m pip install --upgrade pip’ command.
