在Tensorflow安装完成后，为了检查是否安装成功时出现以下问题

Please make sure the missing libraries mentioned above are installed properly if you would like to use GPU. Follow the guide at https://www.tensorflow.org/install/gpu for how to download and setup the required libraries for your platform.
Skipping registering GPU devices…
2021-10-31 22:15:54.090138: I tensorflow/core/platform/cpu_feature_guard.cc:142] This TensorFlow binary is optimized with oneAPI Deep Neural Network Library (oneDNN) to use the following CPU instructions in performance-critical operations: AVX AVX2
To enable them in other operations, rebuild TensorFlow with the appropriate compiler flags.
a = tf.constant([[1,2],[3,4]])
b = tf.constant([[5,6],[7,8]])
c = tf.matmul(a,b)
print(c)
tf.Tensor(
[[19 22]
[43 50]], shape=(2, 2), dtype=int32)
从以上报错中，可以发现，在安装TENSORFLOW时，有很多使用GPU需要的库没有安装。
然后我运行了下面的代码查看了tensorflow的版本，以及GPU能否使用，结果如下：
import tensorflow as tf
import os
os.environ[‘TF_CPP_MIN_LOG_LEVEL’]=’2′
print(tf.version)
2.6.0
a = tf.constant(1.)
b = tf.constant(2.)
print(a+b)
tf.Tensor(3.0, shape=(), dtype=float32)
print(‘GPU:’, tf.test.is_gpu_available())
WARNING:tensorflow:From
为了解决以上问题，我们需要更换安装的tensorflow版本，或者下载缺失的库：
这里我只下载了 cudart64_110.dll ，可以在这个网站上免费下载 免费下载缺失的 DLL 文件 | DLL‑files.com (dll-files.com)
因为没有找到其他缺失的库，我就没有下载了，直接将下载好的库放在路径D:\Anaconda3\envs\tf_gpu\Library\bin（根据自己存放的位置而定）
运行结果如下
import tensorflow as tf
import os
os.environ['TF_CPP_MIN_LOG_LEVEL']='2'
print(tf.__version__)
a = tf.constant(1.)
b = tf.constant(2.)
print(a+b)
print('GPU:', tf.test.is_gpu_available())
查看到自己的GPU信息，说明安装成功，只是缺少的库还没有添加，这个只能后续添加了。
