Tensorflow s'entraîne sur le processeur au lieu du GPU de la série RTX 3000
J'essaie de former mon modèle tensorflow sur mon GPU RTX 3070. J'utilise un environnement virtuel anaconda et l'invite montre que le GPU a été détecté avec succès et n'affiche aucune erreur ou avertissement, mais chaque fois que le modèle commence à s'entraîner, il utilise le processeur à la place.
Mon invite Anaconda:

Mon code modèle:
inputs = keras.Input(shape=(None,), dtype="int32")
x = layers.Embedding(max_features, 128)(inputs)
x = layers.Bidirectional(layers.LSTM(64, return_sequences=True))(x)
x = layers.Bidirectional(layers.LSTM(64))(x)
outputs = layers.Dense(1, activation="sigmoid")(x)
model = keras.Model(inputs, outputs)
model.compile("adam", "binary_crossentropy", metrics=["accuracy"])
model.fit(x_train, y_train, batch_size=32, epochs=2, validation_data=(x_val, y_val))
J'utilise:
- tensorflow nightly gpu 2.5.0.dev20201111 (installé sur un environnement virtuel anaconda)
- CUDA 11.1 (cuda_11.1.1_456.81)
- CUDNN v8.0.4.30 (pour CUDA 11.1)
- python 3.8
Je sais que mon GPU n'est pas utilisé car son utilisation est à 1% tandis que mon CPU est à 60% avec son processus principal étant python.
Quelqu'un peut-il m'aider à obtenir mon modèle de formation en utilisant le GPU?
Réponses
Vous utilisez très probablement Tensorflow pour le processeur, au lieu de celui pour le GPU. Faites un "pip uninstall tensorflow" et "pip install tensorflow-gpu" pour installer celui qui convient à l'utilisation du GPU.
