I'm having the similar problem when I run import tensorflow as tf
After downgrading to the tensorflow 1.5 version, it doesn't have this problem.
Try running:
pip uninstall tensorflow
And then
pip install tensorflow==1.5

Please start Spyder from a terminal, and paste the error messages shown there.

Hi @ccordoba12 , I am getting the same exact error. I just start Spyder and the kernel dies several times (about seven!) before being available. I use the latest Anaconda distrib on a windows 64bit machine

@ccordoba12 I am behind a firewall, and therefore I disabled the option to check for updates at startup. Also I just run spyder --reset in the command line, restarted all over and the problem persists. All dependencies are OK as well. Could this be due to some network issue?

Last, @ccordoba12 starting spyder via the terminal does nothing. I still see Kernel died, restarting... 6/7 times before actually seeing

@randomgambit, this is a duplicate of issue #3444, so I'm closing it. Please add further comments on that issue :-)

Please run Spyder from a terminal (i.e. cmd.exe on Windows) with this command

spyder --show-console

and post the errors you're seeing in the terminal.

spyder --show-console

Starting Spyder from console just opens spyder and "Connecting to kernel" is displayed for long.. No messages in the terminal

im using Spyder 3 and Python 3.6 running on windows 7 ... and i have got the same error "Kernel died, restarting"
the problem was something related to Python. it was unable to run because of some windows feature need to be up to date "mainly Service Pack 1" ... i used that windows file update to solve the problem and it worked very well Windows6.1-KB2999226-x64

I had Anaconda 3.5 (32 bits) for a Win(64 bits) computer. It was working perfectly. At that time I was careful enough to download both 32 and 64 bit versions of Anaconda 3.5. Today I needed to install 64 bits version and updated to 3.6 from command window. I had then this problem of kernel dying. I deinstalled and reinstalled Anaconda 3.5 for 64 bits and Spyder works well without updating.

I reinstalled Tensorflow using the below pip command and it started working for me.
pip install --ignore-installed --upgrade tensorflow-gpu

fyi, I am using the gpu version of tensorflow.

I have this same issue when any Qt window is opened. After the kernel restarts the window will run.
Anaconda 1.8.7
Spyder 3.2.8
Python 3.7

I have this same named issue Kernel died, restarting... but in my case it 's a memory overload that break the kernel.
Example: I try to display a very big image in the kernel.

import imageio
import matplotlib.pyplot as plt

im = imageio.mimread('image.tif')
plt.figure(figsize=(2048,2048)) #int this case, 2048 inch, it's a very big image!
plt.imshow(im[1])

-> Kernel died, restarting

I understand why the kernel die, but the console should return a message like memory overload.

try whether there is any python file recently created has predefined keywords

for me creating a python file logging.py created the issue,
Kernel died, restarting...
Kernel died, restarting...
Kernel died, restarting...
Kernel died, restarting...

i changed filename to user_logging.py which resolved the issue for me

check whether you are overloading any predefined packages of python
