Kernel appears to have died on fitting the model

I have the code like this:

# importing the libraries
import numpy as np
from lightfm.datasets import fetch_movielens
from lightfm import LightFM as lf

# fetch data and format it
data = fetch_movielens(min_rating=5.0)

# print training and testing data
print(repr(data["train"]))
print(repr(data["test"]))

# creating and fitting the model
model = lf(loss="warp")
model.fit(data["train"], epochs=30, num_threads=2)

And I always receive an error “Kernel appear to have died” on the line “model.fit” System is Ubuntu, IDLE is jupyter notebook. I tried to reduce the number of epochs to 1 and the number of threads to 1, but it still doesn’t work. What can be a problem?

Finally, conda install gxx_linux-64 solved my problem. Thanks.

The Intel Core designation covers quite a lot of different CPUs with different architectures. In this case I suspect you have a CPU that’s older than the CPUs used to build the wheels (maybe it doesn’t support AVX instructions?).

The solution is to have a working C compiler and install from source, which is what installing from pip does.

I am using Intel i7. Normally, pip install works for a lot of libraries like keras, numpy, matplotlib, etc. It’s just lightfm which doesn’t want to be installed on my machine.
