Bonjour,
Je souhaite utiliser tensorflow2.0, mais après son installation, le module ne fonctionne pas correctement. J'ai suivi l'installation ici :
https://www.tensorflow.org/install/pip
Lors de la vérification voici le résultat :
(env) rouyrrerodolphe@adm1:~$ python -c "import tensorflow as tf;print(tf.reduce_sum(tf.random.normal([1000, 1000])))"

tf.Tensor(-1710.3865, shape=(), dtype=float32)
L'erreur à la deuxième ligne me laisse penser que mon installation de nvidia/cuda est défectueuse.
La commande nvidia-smi ne fonctionne pas non plus :
rouyrrerodolphe@adm1:~$ nvidia-smi
NVIDIA-SMI has failed because it couldn't communicate with the NVIDIA driver. Make sure that the latest NVIDIA driver is installed and running.
Le problème vient certainement du driver car il n'apparait pas avec la commande ubuntu-drivers devices :
rouyrrerodolphe@adm1:~$ ubuntu-drivers devices
== /sys/devices/pci0000:00/0000:00:1c.0/0000:01:00.0 ==
modalias : pci:v00008086d000024F3sv00008086sd00000050bc02sc80i00

manual_install: True
driver : backport-iwlwifi-dkms - distro free
Mon secure boot est désactivé, j'ai déjà essayé de désintaller et de réinstaller cuda et nvidia. Je ne pouvais pas intallé le pilote propriétaire à partir du dépôt officiel et je n'arrivais pas non plus avec le ppa donc il me semble l'avoir fait via le site de nvidia en suivant ce tuto :

Autre chose surprenante, la commande suivante ne marche plus depuis ma réinstallation de nvidia alors qu'elle fonctionnait très bien avant :
rouyrrerodolphe@adm1:~$ dpkg -l *nvidia* | grep ^ii
