getting ModuleNotFoundError: No module named 'rcute_cozmars' ?

I'm getting this error ModuleNotFoundError: No module named 'rcute_cozmars' when I excute import rcute_cozmars

I installed SDK already using python3 -m pip install rcute-cozmars

Can anyone help me solve this issue? Thanks.

obviously not successfully installed. Or you install it using python3, but import it using python2?

@hyansuper I use the latest Rasbian version with python 3.9 only. I'm trying again but this time installation takes so long time more than 24 hours freezing. which version of Rasbian should I use? did you compile OpenCV and OpenCV Contrib from source? if so, can you give me a link to the tutorial because raspberry pi zero is different from other versions of RPI?

• I tried with another RPI zero w (Rasbian buster) after installing rcute-cozmars-server. but have this error python3 -m pip install rcute-cozmars

Oh，sorry I didn't clarify, rcute-cozmars is meant to be installed on pc, it's a client program that talks to the server on pi zero

@hyansuper thanks a lot. I Installed it on PC. but when I try to control the robot using the website: http://rcute-cozmars-xxxx.local all the buttons are not working.

• I tested all the robot parts separately and they work (servo, dc motors and LCD)
• I make sure all the used bins are correct at conf.json
• the LCD shows "cozmars and the 4 digits"
• why do you think the robot is not responding?

Now you can visit http://rcute-cozmars-xxxx.local/, so wifi connection is good. Click the test button or visit http://rcute-cozmars-xxxx.local/test, open your browser's console (by pressing F12) and goto console and check if any error shows. This page use js api to connect to the robot. You can also close the page and control the robot by python from you pc, example. see if any errors accur

• I visited the website http://rcute-cozmars-d039.local/ and went to the test page to test motors and lcd but when I press any button nothing happen.
• I tried accessing the robot using sdk, it connect successfully but the console is freezing when I use robot.forward(2) See the comments in the next code

  >>> from rcute_cozmars import Robot # works fine
  >>> robot = Robot(d039)  # works fine
  >>> robot.connect() # works fine
  >>> robot.forward(2) # freez the console and motor not moving
  >>>

• also when I connect using python sdk, the eyes are not shown in the lcd. It only show "cozmars and the 4 digits"

I need to see the error message. Login raspberry pi zero and stop backgroud service by sudo systemctl stop cozmars.service then bring it up in foreground sudo python3 -m rcute_cozmars_server. Now you can see if there's any error message on the server side. Then try to control the robot from browser or by python ( you can't do both at the same time), and also watch out for any error on client side.
