- TensorFlow is built with CUDA 10.1.243, not CUDA 10.0.130. Attempts to use the latter failed. Should find a way to make EasyBuild look for a non-standard CUDA location.
- Check whether using gompi instead of gompic (with CUDA) leads to problems with multi-node training. Multi-GPU training on a single node is confirmed to work.
