- Check your devices are recognised even if they're not "managed":
sudo iwconfig
- Check your wifi (here called "wlp3s0") is capable of detecting nearby routers:
sudo iwlist wlp3s0 scan
- Configure

"Building powerful image classification models using very little data" | |
from blog.keras.io. | |
It uses data that can be downloaded at: | |

In our setup, we: | |
- created a data/ folder | |
- created train/ and validation/ subfolders inside data/ | |
- created cats/ and dogs/ subfolders inside train/ and validation/ | |
- put the cat pictures index 0-999 in data/train/cats |
