The kernel appears to have died. It will restart automatically - Running the learning lenet example

[Sandesh Yapuram]

I'm trying to execute the caffe example script from here

Everything seems to be fine as I've installed caffe just few minutes back ..... But this message pops up when I run line 7

"The kernel appears to have died. It will restart automatically."

This is the code:

caffe.set_device(0)
caffe.set_mode_gpu()

### load the solver and create train and test nets
solver = None  # ignore this workaround for lmdb data (can't instantiate two solvers on the same data)
solver = caffe.SGDSolver('mnist/lenet_auto_solver.prototxt')

I'm running and have compiled caffe on CPU_ONLY=1 .... so
I feel the set_mode_gpu() is creating a problem/...
What modifications should I make?

[Sandesh Yapuram]

Solved!

caffe.set_device(0)
caffe.set_mode_gpu()

### load the solver and create train and test nets
solver = None  # ignore this workaround for lmdb data (can't instantiate two solvers on the same data)
solver = caffe.SGDSolver('mnist/lenet_auto_solver.prototxt')

Changed the red portion to

caffe.set_mode_cpu()

Hi Sandesh,

Sorry, this is not a solution. You changed from running it in the GPU to the CPU. 

I am facing same problem just with the following line when trying to set it up to run in the GPU:

caffe.set_device(0)

The kernel dies, anyone with similar problem / solution?

Thank you

Hello Blanca,

Yes I agree with you. I had gotten that same issue in my other machine too.

But this time I ran the code in jupyter-qtconsole and normal jupyter command line. So the error message and its details were displayed right away on the console itself. I suggest you to run the code on console first to identify the error. Because the browser notebook exits without error statement and details.

Regards
