ModuleNotFoundError：Jupyter Notebook 没有名为“keras”的模块

Question

I was running Jupyter Notebook and the following error occurs

ModuleNotFoundError
Traceback (most recent call last) in ---->

from keras.models import Sequential

from keras.layers import (
Conv2D, MaxPooling2D, Flatten, Dense, Dropout)

ModuleNotFoundError: No module named 'keras'

I have tried using import sys; sys.path import sys; sys.path and found this

['/home/xxx/notebook',
 '/home/xxx/anaconda3/lib/python37.zip',
 '/home/xxx/anaconda3/lib/python3.7',
 '/home/xxx/anaconda3/lib/python3.7/lib-dynload',
 '',
 '/home/xxx/anaconda3/lib/python3.7/site-packages',
 '/home/xxx/anaconda3/lib/python3.7/site-packages/IPython/extensions',
 '/home/xxx/.ipython']

Is there any problem with the installation? Do I need to reinstall everything from python to anaconda. Would some be able to point me to a proper installation of anaconda

BTW, if u have installed python, should you install python package through anaconda again

Thanks

Answer 1

You have to install all the dependencies first before using it. Try using

• conda install tensorflow
• conda install keras

by installing it with conda command it manage your versions compatibility with other libraries.

with pip install libraries will only install in your current environment and the latest version of the library sometimes latest libraries are not compatible with the other libraries so we have to take care of version compatibility.

Answer 2

keras is actually part of tensorflow so all you have to do is just

from tensorflow.keras.models import Sequential

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

Answer 3

Create a virtual environment and install all packages and specially jupyter-notebook in it. Some times it is necessary to install jupyter-notebook in each virtual environment to work properly with other libraries. It is preferred to use anaconda .

After creating your virtual env use this command to install jupyter:

conda install -c anaconda jupyter

Answer 4

If you have installed all the required packages in a virtual/conda environment, have you tried saving the environment as an ipython kernel? I got those errors when I tried to launch a jupyter notebook from my virtual environment but I hadn't explicitly created a kernel for it.

Answer 5

在 Anaconda Navigator -> Enviroments -> Play 按钮 -> Open Terminal -> conda install keras 中安装包

Answer 6

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

These two import statements worked for me.
