#1

I’m getting the following errors:

That happens every time I run this, or I get to this point in the code:

pred = model.predict(x)
print(pred)

When I run the next code I get the following output.

#2

This has been run in a MacBook Pro mid 2015 i7 2.8 16GB. I thing this machine is capable of running this simple program.

Thank you!

#3

When you get the “Kernel Restarting” message, it means that Python has crashed. Unfortunately, it doesn’t really tell you why but it’s likely that there was a problem with Keras or TensorFlow.

Does the Terminal window from which you launched Jupyter notebook show any messages?

(By the way, after such a crash happens, you will need to run every cell in the notebook again, you can’t just continue with the next one.)

#4

Hi,

I have the same problem. ‘The kernel appears to have died. It will restart automatically’.
Does anyone have an idea how to fix it?

The error occurs when executing

pred = model.predict(x)
print(pred)

In the terminal I see the following log output:

OMP: Error #15: Initializing libiomp5.dylib, but found libiomp5.dylib already initialized.
OMP: Hint: This means that multiple copies of the OpenMP runtime have been linked into
the program. That is dangerous, since it can degrade performance or cause incorrect
results. The best thing to do is to ensure that only a single OpenMP runtime is linked into
the process, e.g. by avoiding static linking of the OpenMP runtime in any library. As an
unsafe, unsupported, undocumented workaround you can set the environment variable
KMP_DUPLICATE_LIB_OK=TRUE to allow the program to continue to execute, but that may
cause crashes or silently produce incorrect results. For more information, please see

I could eventually fix it. I did some Googling and after a bit of trial/error I got it working. It seems it’s a macOS only problem that occurs on Mojave.
The fix was adding this to the import statements at the top of the notebook:

import os
os.environ['KMP_DUPLICATE_LIB_OK']='True'
