Installation GPU RTX 3060 - Tensorflow

Bonjour
J'ai récemment acheté un PC avec une RTX 3060 et je souhaite faire du deep learning.
J'ai suivi l'installation suivante:

https://www.tensorflow.org/install/pip

Mais à la commande:

python3 -c "import tensorflow as tf; print(tf.config.list_physical_devices('GPU'))"

J'ai le résultat suivant:

I tensorflow/core/platform/cpu_feature_guard.cc:193] This TensorFlow binary is optimized with oneAPI Deep Neural Network Library (oneDNN) to use the following CPU instructions in performance-critical operations:  AVX2 FMA
To enable them in other operations, rebuild TensorFlow with the appropriate compiler flags.

Pouvez m'aider à installer le GPU ?

Re : Installation GPU RTX 3060 - Tensorflow

Salut,
tensorflow ne trouve pas les deux librairies dans LD_LIBRARY_PATH, on va déjà voir si elles existent sur ton système:

sudo find / -name "libnvinfer.so.7" 2>/dev/null
sudo find / -name "libnvinfer_plugin.so.7" 2>/dev/null

Il y a deux possibilités: les fichiers n'existent pas sur ton disque, il faut alors installer le bon paquet qui permettra d'avoir ces fichiers, ou les fichiers existent, et il faudra adapter LD_LIBRARY_PATH

Merci,
je pense  avoir résolu le problème en réinstallant Cuda CNN !
Cela n'a pas été facile !
