AttributeError:没有属性“BatchNormalizationBase”

Question

当我运行脚本时，出现了错误

File "akurasi.py", line 3, in <module>
import keras
    File "C:\projeku\Lib\site-packages\keras\__init__.py", line 21, in <module>
from tensorflow.python import tf2
    File "C:\projeku\Lib\site-packages\tensorflow\__init__.py", line 41, in <module>
    from tensorflow.python.tools import module_util as _module_util

    from tensorflow.python import keras
  File "C:\projeku\Lib\site-packages\tensorflow\python\keras\__init__.py", line 25, in <module>
    from tensorflow.python.keras import models

    from tensorflow.python.keras import metrics as metrics_module
  File "C:\projeku\Lib\site-packages\tensorflow\python\keras\metrics.py", line 37, in <module>
    from tensorflow.python.keras import activations
  File "C:\projeku\Lib\site-packages\tensorflow\python\keras\activations.py", line 18, in <module>
    from tensorflow.python.keras.layers import advanced_activations
  File "C:\projeku\Lib\site-packages\tensorflow\python\keras\layers\__init__.py", line 147, in <module>
    from tensorflow.python.keras.layers.normalization_v2 import SyncBatchNormalization
  File "C:\projeku\Lib\site-packages\tensorflow\python\keras\layers\normalization_v2.py", line 29, in <module>
    class SyncBatchNormalization(normalization.BatchNormalizationBase):
AttributeError: *module 'tensorflow.python.keras.layers.normalization'* has no attribute **'BatchNormalizationBase'**

在我的脚本中没有“importtensorflow.python.keras.layers.normalization”。谁能帮帮我吗？如何解决这个问题？谢谢：）
