Re: Pi4, Coral TPU, TensorFlow. install HadoopFileSystem load error

Yes so far I find Coral and the Pi a useless combination. Once you mess up you need to reload the Pi and OS and start from scratch. I have already spent days struggling to put them together Google is selling their board at $150.00 with a Yocto Linux build which is limiting as to what hardware and to...

Re: Pi4 64-bit raspbian kernel for testing - Focus on Pi4

Is there a central location for the state of the 64 bit version?
A google support engineer told me Tensorflow is dropping 32 bit support. So are there any 64 bit pre-compiled tools available via apt-get?Or do do you have to recompile packages like opencv for a 64 bit kernel?

Pi4 Kodi and remote controls.

I am trying to make a Pi4 Kodi player and thought how do I control it with a nice remote.
I was hoping someone knew of a remote similar to the Fire Stick for small easy manipulation.

What I don't know is if decompression of the video frame or transfer from the GPU memory to CPU memory takes longer than reading in an uncompressed RGB frame to be manipulated.
