Bon finalement Bazel prend des plombes et rien ne semble s’installer… Du coup, comme je suis en python 3.7, je tente celle là: https://github.com/lhelontra/tensorflow-on-arm/releases/download/v1.14.0-buster/tensorflow-1.14.0-cp37-none-linux_aarch64.whl

Next step, let’s build it for real. By the way, kiddoes, don’t try this -j6 at home unless you have a good heatsink… Or the machine will stop/hang up/reboot without prior alert.
make all -j6

Run a simple example
Run the caffe example – mnist instance: Mnist is a handwritten digital library. Originally used for handwritten numeral recognition on checks, and it is now the DL’s starting exercise library. The special model for mnist identification is Lenet, which is the earliest CNN model. The training samples of mnist data are 60,000 units, and the test samples are 10,000 units. Each sample is a black and white picture of size 28*28, and the handwritten number is 0-9, so it is divided into 10 categories.
Download the mnist data first
sh data/mnist/get_mnist.sh
cd data/mnist
There are four files in the directory after running the previous command:

These data cannot be used directly in Caffe, and need to be converted into LMDB data:
