Hi,
In trying the controller example to enable remote control an error is coming up when running the example.
picar x ModuleNotFoundError: No module named ‘tflite_runtime’
I have looked online and it talks about virtual environments etc to install tflite.
Is there a way to install tflite to get the controller example working?
It is highly likely that during your previous installation of the library code, tflite_runtime was not successfully installed, which caused the error message when running the sample code.
We recommend that you reinstall all the library code by following the tutorial steps and then run the sample code again.
If any installation fails during the process, please provide us with the complete error message so that we can help you analyze and resolve the issue.
Thank you for your reply. I will reinstall and advise any noted errors.
Hi,
I reinstalled and here is the collection of commands and output where appropriate. The exact same error occurred.

The issue is reported near the top of your log file….
sg23Python version: 3.13.5Raspbian version: 13 (64bit) mediapipe is only supported on 64bit system with python 3.12 or older.tflite-runtime is only supported on python 3.12 or older
You’ll need to downgrade your OS to pick up python <= v3.12
I’d suggest bookworm
Thank you. I installed bookworm 32bit and reached the point of installing vilib.
mediapipe is only supported on 64bit system with python 3.12 or older.

Thank you. I have reached the point of running the controller example fine. The android phone is not reaching the picarx.

Please provide us with a video of the issue and the operating process so that we can better help you analyze and resolve the problem.
Probably irrelevant, but a 10.x.x.x ip address is usually for a larger e,g work/business type network. Home use is more usually something like 192.168.x.x, just wondering if your “work” network is blocking anything?
Total shot in the dark though!
Interesting thought. It is hotspoting through a phone so that could be something to do with it.
I will do that. I will finish changing the wifi first - just in case the hotspot phone is an issue here. If you change the wifi only is there a way to update that setting without having to reinstall the whole sd card?
Yes. You can connect your Raspberry Pi to a display, mouse, and keyboard, and then change the Wi‑Fi network connection directly on the desktop of the system.
Thank you for that.
Exitingly adding a wifi (rather than hotspotting the mobile phone) did the job. It works perfectly.
Thank you @Spf650 and @SunFounder_Moderator for your help.
oh @Spf650 ip is 192.168 etc
