Building TensorFlow from source (TF 2.3.0, Ubuntu 20.04)

Why build from source?

The official instructions on installing TensorFlow are here: https://www.tensorflow.org/install. If you want to install TensorFlow just using pip, you are running a supported Ubuntu LTS distribution, and you're happy to install the respective tested CUDA versions (which often are outdated), by all means go ahead. A good alternative may be to run a Docker image.

I am usually unhappy with installing what in effect are pre-built binaries. These binaries are often not compatible with the Ubuntu version I am running, the CUDA version that I have installed, and so on. Furthermore, they may be slower than binaries optimized for the target architecture, since certain instructions are not being used (e.g. AVX2, FMA).

So installing TensorFlow from source becomes a necessity. The official instructions on building TensorFlow from source are here: ht

Using ffmpeg-3.1.6-1.fc25.x86_64 on Fedora 25, available from rpmfusion-free repo. It has been built with va-api support.

The following ffmpeg invocation works for me.

ffmpeg -hwaccel vaapi -hwaccel_output_format vaapi -vaapi_device /dev/dri/renderD128 \
   -i input.mkv -vf 'format=nv12,hwupload' -map 0:0 -map 0:1 -threads 4 \
   -acodec copy -vcodec h264_vaapi -qp:v 23 \
   output.mp4

Here's my setup:

• Home server running Ubuntu 14.04.5 LTS (GNU/Linux 3.13.0-93-generic x86_64)
• Plex Media Server debian package running on server
• Netgear Nighthawk R6900 home router
• Dynamic hostname from no-ip.org, which I'll use for this setup

So, the way this goes is I post my AVR  code, then I post what the HTC Vive does.

The output is:  POST 0: (# of bytes) (IMU Timecode MSBs) (All raw light data)

(All raw light data ends with [3 bytes, LSB timecode] [OTA CRC (probably ignore)])

Events (TIME): (LED CODE 1)/(TIME CODE 1/TIMECODE 2)/(LED CODE 2)/(TIME CODE 3/TIMECODE 4)...
//NOTICE: The funky encoding of the numbers, and the fact that paramters are read from the end of the data going forward.
//We know we're done when the # of parameters read is (# of bytes left*2)-1
