I'm trying to import keras and the code returns an error about tensorflow.
import numpy
import matplotlib.pyplot as plt
import pandas
import math
from keras.models import Sequential
from keras.layers import Dense
and the error says:
Using TensorFlow backend.

ModuleNotFoundError: No module named 'tensorflow'
It seems like tensorflow is not found. You need to install tensorflow in order to use keras library.
If you already installed tensorflow, try to uninstall and install it again.
sudo pip3 uninstall tensorflow
pip3 install --upgrade tensorflow
You can verify the install by running this command:
python3 -c "import tensorflow as tf; print(tf.reduce_sum(tf.random.normal([1000, 1000])))"
This error is related to TensorFlow. TensorFlow may not be installed or installed incorrectly. please check TensorFlow installation

The error is due to a glitch happening during the update due to pip. Related SO post is https://stackoverflow.com/a/59355676/6513708
But long story short, you need to remove the following files which were let by pip during the update:
~/.local/lib/python3.6/site-packages/sklearn/decomposition/_online_lda.cpython-36m-x86_64-linux-gnu.so

if K.backend() == 'tensorflow' and not K.tensorflow_backend._is_tf_1():
AttributeError: module 'keras.backend.tensorflow_backend' has no attribute '_is_tf_1'
I fix this problem by replacing keras.XXX to tensorflow.keras.XXX
try replace
import keras.backend as K
to
import tensorflow.keras.backend as K
import this:
import tensorflow as tf
then use
tf.compat.v1.keras.backend.
as prefix of your desired attribute
I had the same error and tried installing and uninstalling. In the end, I found that the library was not actually installed correctly.
I went through each library in my:
C:\Users\MyName\AppData\Local\Packages\PythonSoftwareFoundation.Python.3.8_qbz5n2kfra8p0\LocalCache\local-packages\Python38\site-packages\
I tracked down the file in within the site-packages in Keras, which was calling from the Tensorflow library, which was calling from another folder. I found the final folder had the get_session(), but this was not being called in. When I checked the directory, I found that get_session wasn't being loaded in. Within the file directory /tensorflow/keras/backend.py it was importing everything, but missed out the get_session.
To fix this I added this line:
from tensorflow.python.keras.backend import get_session
Then saved it. The next time I ran my code it was fine. I would suggest doing similar with your files, locating where the attribute is called in and making sure it is being imported.
pip3 uninstall keras
pip3 install keras --upgrade

installing TensorFlow 1.14.0 + Keras 2.2.5 on Python 3.6 fix this
make sure your keras version is right. if your backbend is tensorflow,you can
import tensorflow as tf
print(tf.VERSION)
print(tf.keras.__version__)
get the right version of keras,then install this version,I fix this problem by this way,i hope my answer can help you.
When I tried to import torchvision, I got an import error.
I googled this problem but found nothing except that the problem may be in Cython. StackOverflow search didn't found anything either. How can I solve this?
Torchvision version is 0.3.0.

Try this for anaconda:
conda install torchvision -c pytorch
Using pip:
pip install torchvision
Problem solved: the problem was in Python 3.5, using Python 3.6 solves problem.
import matplotlib.pyplot as plt
from sklearn import datasets
from sklearn import svm
it gives the following error-
Traceback (most recent call last):

File "/home/songoku/PycharmProjects/untitled/sklearn.py", line 4, in <module>

Rename /home/songoku/PycharmProjects/untitled/sklearn.py to something that differs from the SKLearn module name: sklearn.py
Try checking the version of sklearn first. The modules like data-sets and svm is not a part of sklearn packages (0.19 <) i.e less than version number 0.19.0.
You can check this on the command line: pip3 list
it shows you the version of all libraries installed by pip3.
Note: Always double check if you istalled the libraries as a part of anaconda or pip3
I have Anaconda 4.3.1 installed in my laptop after the commands cd /home/username/anaconda3and source bin/activate ~/anaconda3 my package starts .
And I installed keras using pip3 conda install keras inside my anaconda. package.and made a document named keras.json inside my keras folder.
When I start my Python in anaconda3 and import keras this happens

After following this I could not get any solution. I would appreciate any help.
I had this same exact issue (I was using pip instead of conda to install keras / tensorflow, however). Make sure you have the most up-to-date version of tensorflow (tensorflow-1.0.1 as of March 31st, 2017).
sudo pip install tensorflow --upgrade
fixed the problem for me (I was running tensorflow-0.9.0rc0 before and was getting the same ImportError: cannot import name ctc_ops error as you)
