【琐碎】查看tensorflow安装版本、位置信息及是GPU版本还是CPU版本

tensorflow的安装版本和安装位置

import tensorflow as tf
# 查看安装的tensorflow的版本
print(tf.__version__)
# 查看安装的tensorflow所在的位置信息
print(tf.__path__)

输出结果

2.3.0
['E:\\apps\\Anaconda3\\envs\\dome\\lib\\site-packages\\tensorflow', 'E:\\apps\\Anaconda3\\envs\\dome\\lib\\site-packages\\tensorflow_estimator\\python\\estimator\\api\\_v2', 'E:\\apps\\Anaconda3\\envs\\dome\\lib\\site-packages\\tensorboard\\summary\\_tf', 'E:\\apps\\Anaconda3\\envs\\dome\\lib\\site-packages\\tensorflow', 'E:\\apps\\Anaconda3\\envs\\dome\\lib\\site-packages\\tensorflow\\_api\\v2']

查看tensorflow所有的设备信息

import os
from tensorflow.python.client import device_lib
os.environ["TF_CPP_MIN_LOG_LEVEL"] = "99"

if __name__ == "__main__":
    rs=device_lib.list_local_devices()
    print(type(rs))
    print(rs)

运行结果

查看Tensorflow-GPU是否可用，可用用于验证tensorflow-gpu是否安装成功

import tensorflow as tf
print(tf.test.is_gpu_available())

输出结果

True

查看GPU设备名

import tensorflow as tf
gpu_device_name = tf.test.gpu_device_name()
print(gpu_device_name)

输出

/device:GPU:0

查看所有GPU信息

from tensorflow.python.client import device_lib
# 列出所有的本地机器设备
local_device_protos = device_lib.list_local_devices()
# 打印
# print(local_device_protos)
# print("------------------")
# 只打印GPU设备
rs=[x for x in local_device_protos if x.device_type.find('GPU')!=-1]
print(rs)
