I've started running train configs configs/zipnerf/360.gin & configs/camp/camera_optim.gin on google colab free gpu tier A single scene with the default 200k iterations will take about 3 days, is that what...

it looks like you run on TPU (google colab ?) try switching to GPU runtime, as JAX is not working properly

could replace 'implementation' by developmentOnly , unless you want it also present for launches other than bootrun

thanks, I"m also blocked at the moment, maybe this [colab](https://gist.github.com/Brunwo/90375eaddec7aa045bd637d10e26844d) can serve as a starting point, still a draft : remaining issues are getting the data in the right format...
