cannot import name 'BatchNormalization' from 'keras.layers.normalization' - python

I'm learning ObjectDetection from this website
I have installed ImageAI,Tensorflow and Keras.
Then when I run this in python
from imageai.Detection import ObjectDetection
I got
Traceback (most recent call last):
File "", line 1, in
File "/home/carl/python-environments/env/lib/python3.9/site-packages/imageai/Detection/init.py", line 17, in

ImportError: cannot import name 'BatchNormalization' from 'keras.layers.normalization' (/home/carl/python-environments/env/lib/python3.9/site-packages/keras/layers/normalization/init.py)
Already tried:
from keras.layers.normalization.batch_normalization import BatchNormalization
from tensorflow.keras.layers import BatchNormalization
But still gave me the same error.

Tensorflow v2.8.0 support tf.keras.layers.BatchNormalization()
import tensorflow as tf
tf.keras.layers.BatchNormalization()

Tensorflow/Keras - ImportError: cannot import name 'Sequence'

Trying to run some machine learning examples so am importing some packages
sklearn version 0.22.1
tensorflow version 2.3.0
keras version 2.3.0
in the following way:
import os
import sys
import math
import numpy as np
import pandas as pd
from sklearn.preprocessing import MinMaxScaler
from keras.models import Sequential
from keras.layers import Dense, LSTM
import matplotlip.pyplot as plt
I am getting the import error:

I have looked on line for help trying a few different tensorflow and keras versions. I have also tried:
import tensorflow.keras as keras
and import tensorflow.keras.utils import Sequence
without success

Cannot import name SummaryWriter

I'm using Pycharm with python 3.9, torch 1.8.1+cu111 and tensorboard 2.6.0.
When I try to import SummaryWriter by:
from torch.utils.tensorboard import SummaryWriter
I get the following error:

writer = SummaryWriter('runs/mnist')

Bro
I have just solved a similar problem like yours. Just ensure that your filename is not set as 'tensorboard'.

Tensorflow 2.0: Cannot Import tf.keras.utils.conv_utils

I'm using Tensorflow v2.1.0 which is compiled from source. How can I import any function from conv_utils module? E.g. convert_data_format(), conv_output_length(), normalize_tuple(), etc.
I wanna create my own convolution/pooling layer. "Everything" almost looks different when I wanna migrate from import keras to from tensorflow import keras.
This is what I did
> python -c "from tensorflow.keras.utils import conv_utils"
Traceback (most recent call last):
File "<string>", line 1, in <module>
ImportError: cannot import name 'conv_utils' from 'tensorflow.keras.utils' ...
Thank you.
Try this:
from tensorflow.python.keras.utils import conv_utils
This is the new way to import conv_utils in Tensorflow 2.1.0:
import tensorflow.keras.utils as conv_utils

tensorflow import error can somebody help me

import keras
from keras.models import Model
from keras.layers import Dense, Dropout, LSTM, Input, Activation
from keras import optimizers
import numpy as np
np.random.seed(4)
from tensorflow import set_random_seed
set_random_seed(4)
from util import csv_to_dataset, history_points
Using TensorFlow 2.0 as backend and got following errors.
Traceback (most recent call last):
File "C:/Users/sander/PycharmProjects/autotrader/basic_model.py", line 7, in <module>
from tensorflow import set_random_seed
ImportError: cannot import name 'set_random_seed' from 'tensorflow' (C:\Users\sander\venv\lib\site-packages\tensorflow\__init__.py)
What does this error mean?
set_random_seed is a function not a module, have you tried following steps?
In tf 1.x, do it as this:
import tensorflow as tf
tf.set_random_seed(4)
In tf 2.0, do this as this:
import tensorflow as tf
tf.compat.v1.set_random_seed(4)
