errors_impl.AlreadyExistsError: Another metric with the same name already exists.

今天在导包keras包时，总是报上面这个错误，说已经keras文件名重复

import keras也不行。

from tensorflow import keras
from tensorflow.keras.applications.vgg16 import VGG16

网上查询各种方法，最后检查我安装的tensorflow-gpu 2.6.0，默认keras 2.8.0

把keras2.8.0版本降到2.6.0解决

(tensorflowgpu) C:\Windows\system32>pip uninstall keras

Proceed (Y/n)? y
  Successfully uninstalled keras-2.8.0

重新安装
