Some LSTM like questions have sparked my neural network curiosity again. Time to dust off that GPU.
Quite a disappointment: my 1.5 years old laptop (tank style HP Zbook) cannot support tensorflow with CUDA 8.0, the CUDA compute capability is 3.0 and it requires 3.5.
HP-Z800 to the rescue! This machine was quite loud, but I managed to install some water cooling, making it sound less like a server. Compiling tensorflow sucked the live out of this dual cpu machine. O.k., it is only twice six cores, but still: 1042s.

A restart fixed some scary kernel messages, and presto we have flow:
