Answers for "import tensorflow gpu"

gpu training tensorflow

import tensorflow as tf
print("Num GPUs Available: ", len(tf.config.experimental.list_physical_devices('GPU')))

tensorflow use gpu

python -c "import tensorflow as tf; print('Num GPUs Available: ', len(tf.config.experimental.list_physical_devices('GPU')))"

install tensorflow gpu

pip3 uninstall tensorflow
pip3 install 'tensorflow-gpu==1.15.4'

config allow growth tensorflow

# Assume that you have 12GB of GPU memory and want to allocate ~4GB:
gpu_options = tf.GPUOptions(per_process_gpu_memory_fraction=0.333)

sess = tf.Session(config=tf.ConfigProto(gpu_options=gpu_options))

do i need do some set when i use GPU to train tensorflow model
