Describe the expected behavior

No error when importing keras.

Code to reproduce the issue

import keras

[AnkitRai]

Experiencing a similar issue, while importing keras

[AAAA11111333355]

STEP 1: CREATING NEW ENVIRONMENT

open anaconda command prompt

*type these commands:
a. conda create -n EnvironmentName python=3.5 anaconda
Example (base) C:UsersAsus>conda create -n py35 python=3.5 anaconda
b. Activate EnvironmentName : type command: activate py35
Example (base) C:UsersAsus>activate py35

STEP 2: INSTALL SPYDER ON NEW ENVIRONMENT

open anaconda command prompt

*type this command: conda install spyder
Example (py35) C:UsersAsus>activate py35

STEP 3: INSTALL THEANO TO NEW ENVIRONMENT OF ANACONDA NEGIVATOR

open anaconda command prompt

*type this command: conda install theano
Example (py35) C:UsersAsus>conda install theano

STEP 4:INSTALL TENSORFLOW TO NEW ENVIRONMENT OF ANACONDA NEGIVATOR

open anaconda command prompt

*type this command: conda install tensorflow
Example (py35) C:UsersAsus>conda install tensorflow

STEP 5: GET TENSORFLOW FOR *GPU NOT for *CPU (not a complete step)

open anaconda command prompt

*install latest pip if not latest
*type this command: python -m pip install --upgrade pip

STEP 6: INSTALL KERAS
*type command : conda install -c conda-forge keras
Example (py35) C:UsersAsus>conda install -c conda-forge keras

NOW IT SHOULD WORK
Gives warning due to incomplete 5th step
GIVES SOME WARNING BUT WORKS GOOD>>>>>>>>>

It sounds like an installation issue. Please try to uninstall and reinstall Keras:

pip uninstall keras
pip install keras --upgrade

[AAAA11111333355]

I was trying to help others !! No errors on my side

@fchollet following that, now the error is:

Then pip install pyyaml does nothing installs the package but does not resolve the issue.

Note that I'm not adversely affected by this (as I have previously setup environments I can use) but something might have gone wrong recently as this is now manifesting.

[fchollet]

The fact that pip install pyyaml does not fix your import error likely indicates that the Python location used by your pip command and the Python location used by your python command (used to run the script) aren't the same. This is a common environment setup issue.

You can try to run which pip and which python to debug this.

It sounds like an installation issue. Please try to uninstall and reinstall Keras:

pip uninstall keras
pip install keras --upgrade

It works for me! I have been trying others methods

[parikshit223933]

It sounds like an installation issue. Please try to uninstall and reinstall Keras:

pip uninstall keras
pip install keras --upgrade

it worked for my thank you so much!
i run these two commands in conda prompt because i am using python with anaconda. and it worked perfectly fine for me!

[jenniferchiang]

It sounds like an installation issue. Please try to uninstall and reinstall Keras:

pip uninstall keras
pip install keras --upgrade

Thanks a lot. That's truly helped!

[vijayg15]

It works for me, thank you so much!

Worked for me too. Thanks

[ghost]

This could possibly be due to multiple versions of Keras been installed.
Uninstalling Keras and reinstalling it will solve the issue.

[BalajeSenthil]

It does not sort out my issue

[amantorayew]

This issue seems to appear when installing keras (pip install keras) on the Spyder console. When installed on conda prompt, it worked for me.

[iamrachanagupta]

This issue happened to me when I had installed Keras through the Anaconda environment list and then from conda prompt as well. Once I uninstalled Keras from both the places and installed it again from Conda prompt it worked for me.
