Error in code tensorflow is installed

[ErnestTBass]

The following code on Windows 10 creates the error shown.

import math
import numpy as np
import pandas as pd
import os
import yfinance as yf
import matplotlib.pyplot as plt
import matplotlib.gridspec as gridspec
%matplotlib inline
from pandas.plotting import register_matplotlib_converters
register_matplotlib_converters()

from keras.models import Sequential
from keras import layers
from keras.layers import Activation, Dropout, Flatten, Dense, Conv2D, MaxPooling2D

Error:
ModuleNotFoundError                       Traceback (most recent call last)

      2 try:
----> 3     from tensorflow.keras.layers.experimental.preprocessing import RandomRotation
      4 except ImportError:

ModuleNotFoundError: No module named 'tensorflow.keras.layers.experimental'

During handling of the above exception, another exception occurred:

      7         'Install TensorFlow via `pip install tensorflow`')
      8 

ImportError: Keras requires TensorFlow 2.2 or higher. Install TensorFlow via `pip install tensorflow`

However, tensorflow is installed. Both pip list and conda list confirm this.So what is going on? I am using tensorflow 2.3.

Any help appreciated.Thanks in advance.
