## Prevent running out of memory

To prevent running out of memory during a build, restrict the build to use
e.g. 1 processor:
```bash
$ ck install package:lib-tensorflow-2.0.1-src-cuda --env.CK_HOST_CPU_NUMBER_OF_PROCESSORS=1
```

## Known problems
### CUDA 10.2 in not supported

[Downgrade to 10.1](https://github.com/tensorflow/tensorflow/issues/34429).
