Why I can't import this module?

I'm trying to import img_to_array even though all packages are there. This error still appears:
Traceback (most recent call last):
File "c:\Users\Usuario\Downloads\keras-api\keras-main.py", line 11, in <module> from keras.preprocessing.image import img_to_array
ImportError: cannot import name 'img_to_array' from 'keras.preprocessing.image'
This is how I am calling the packages from the keras package.
from keras.preprocessing.image import img_to_array
On the other hand, this is what I'm trying to do with the code.
image = img_to_array(image)
However, I cannot even continue because I'm not able to import img_to_array

but this is how you import img_to_array if you have installed the keras package via e.g. pip install keras
from keras.utils import img_to_array
img_to_array
check if the keras version is the correct one:
Keras Installation Guide

ModuleNotFoundError: No module named 'six.moves.collections_abc'

i am just starting with machine learning i am following this tutorial from Weights&Bias where they gave us some code and asked to run it i am unable to run the code
First I was getting the error
Keras requires TensorFlow 2.2 or higher
for which I tried this method
Following the advice given here, downgrading Keras did the trick for me without having to touch any other packages. Just do:
pip install keras==2.3.0
from this link
Error "Keras requires TensorFlow 2.2 or higher"
then I started getting the error
Using TensorFlow backend.

for which I tried this method
easy_install six
from this link
ImportError: No module named six
but it did not solve my issue

Using this method
pip install --ignore-installed six
From the following link solved the problem for me.
ImportError: No Module named six; six already installed
Although I still don't understand about what was actually wrong and how it got fixed.

keras is not running even after installing tensorflow

i have installed "Anaconda3-2020.07-Windows-x86_64" and python "python-3.8.0". after that, i have installed keras and then tensorflow. but each time i am running the code "import keras" in spyder, the problem is showing that:

----------------------------------------------***
now, i dont know what is the problem mainly. because my tensorflow version shows that its 2.3.0..
i dont know what iis the problem. please, any one help.

From comments
I had to create a environment in anaconda, named the environment as
tensorflow, and created the environment based on python 3.6. In that
environment, i imported tensorflow, keras separately and installed the
spyder, jupyter notebook . after all these steps, it worked (paraphrased from kazi fahim lateef)
Steps to create virtual environment in anaconda
# Create environment
conda create --name TF
# When conda asks you to proceed, type y:
proceed ([y]/n)?
# Activate virtual environment
conda activate TF
# Install the TF Version
conda install tensorflow
# Install the Keras Version
conda install Keras
Note: From TF 2.0, onwards keras are integrated with TF. You can refer tf.keras module for more details.

Unable to import tensorflowjs successfully

I have tensorflow 1.5 and everything is working fine with tensorflow.
Now i want to convert my tensorflow keras model to be used in web app so i installed tensorflowjs successfully but when i import i get the error.
I have tried changing the following versions:
numpy from 1.16.4 to 1.15.1,
tensorflow 1.5.0 to 1.8.0 and 1.12.0,
tensorflowjs 1.1.2 to 1.0.0
tensorflow test:
import tensorflow as tf
print(tf.__version__)
hello = tf.constant("Hello Tensorflow")
with tf.Session() as sesh:
print(sesh.run(hello))
Output:
1.12.0
2019-06-11 12:02:11.140827: I tensorflow/core/platform/cpu_feature_guard.cc:141] Your CPU supports instructions that this TensorFlow binary was not compiled to use: AVX2
b'Hello Tensorflow'
So i guess everything is fine with tensorflow but still i cant import tensorflowjs due to some files missing in my tensorflow installation.
i got this error first:
Traceback (most recent call last):
File "C:/Users/Uxama/PycharmProjects/untitled1/test.py", line 2, in <module>
import tensorflowjs as tfjs
File "C:\Users\Uxama\PycharmProjects\untitled1\venv\lib\site-packages\tensorflowjs\__init__.py", line 21, in <module>

from tensorflow.python.framework import convert_to_constants
ImportError: cannot import name 'convert_to_constants'
Then i placed the file (convert_to_constants) manually because changing the versions doesn't seems to work and change anything.
Then i got this error:
Traceback (most recent call last):
File "C:/Users/Uxama/PycharmProjects/untitled1/test.py", line 2, in <module>

from tensorflow.python.eager import wrap_function
ImportError: cannot import name 'wrap_function'
I did the same thing again and placed the file but the errors seems to kept coming.
I don't know what exactly causing the problem i installed tensorflow with pip and also tried installing it with wheels as well.
I just want to successfully install tensorflowjs so that i can convert my keras model to use in web app.

Tensorflow 1.12 doesn't define a function called wrap_function(). Consider upgrading to API r1.13. Here are the functions defined in API r1.12, which you are currently using, and here is the wrap_function() method which is defined in API r1.13.

ImportError: cannot import name 'Iterator'

I want to run a segmentation code (with this link in github: https://github.com/taigw/brats17) on Google Colab and I'm faced with this error:
/usr/local/lib/python3.6/dist-packages/h5py/__init__.py:36: FutureWarning: Conversion of the second argument of issubdtype from `float` to `np.floating` is deprecated. In future, it will be treated as `np.float64 == np.dtype(float).type`.
from ._conv import register_converters as _register_converters
Traceback (most recent call last):
File "test.py", line 18, in <module>
from tensorflow.contrib.data import Iterator
ImportError: cannot import name 'Iterator'

Try this:
import tensorflow as tf
Iterator = tf.data.Iterator

I suspect this is a version conflict for tensorflow. The data package has been upgraded from tf.contrib.data to a core package tf.data. You are probably using a newer version of tensorflow than that code was developed for. You can install an older version of tensorflow with pip install tensorflow==1.5 (that would install version 1.5 for example).
