RPi Pico mip not installed

[mrks89]

There is no mip on the rpi pico (without Wifi). So how would I install packages or use mip?

Here is a similar issue that you can look at: coin-or/python-mip#276

[Josverl]

Install mpremote on your pc/host
Then use that to install packages to the MCU

pip install mpremote
mpremote mip install my_package

should exist though. At least it is used here e.g.: git example
legit comment, but I have attached a sim7080 pico hat to connect via cat-m and was hoping to use the network package same as in the tutorial mentioned.

The network module exists only on boards with networking support in the hardware and cannot be loaded to other boards. The sample you linked uses obviously such a board. You should be able to use a sim7080 e.g. by UART by sending the proper AT commands and exchanging data, but that would be completely different to the example. There was some discussion for such a method in the forum about setting up a PPP connection. But I did not follow it.

concerning the network package you say that won't work even with the sim module, okay. But that is a special package, what about e.g. numpy, or any other package. And another special package umqtt, won't that also work with my setup?

[robert-hh]

Numpy is a huge package, which requires way more RAM than the ~200k a RPi Pico has. It runs on a RPi3 or 4 with 10000 to 20000 times the RAM size a RPI Pico has. There is a small similar software call ulab, but that has to be built into the firmware. You can install umqtt.robust or umqtt.simple with mip. But umqtt uses sockets, and sockets are available together with the network module. You can tell which modules arte available in the firmware by calling:
help("modules")
at the REPL prompt. if you want to do networking, get e.g. a Pico W module.

okay. I did not understand all this. I have a clearer picture now. Thanks a lot.
