I encountered the following problem in completing my work:

Kernel Restarting
  The kernel appears to have died. It will restart automatically.

Below is the code I ran:

from __future__ import division
 import numpy as np
 import correlation
 from scipy.spatial import cKDTree
 
 File1 = np.loadtxt('/Users/Sidd/Research/fname1.txt')
 File2 = np.loadtxt('/Users/Sidd/Research/fname2.txt')
 
 masscut = 1.1*np.power(10,13)
 mark1 = (np.where(File1[:,0]>masscut))[0]
 mark2 = (np.where(File2[:,0]>masscut))[0]
 
 Data1 = File1[mark1,1:8]
 Data2 = File2[mark2,1:8]
 
 Xi_masscut = correlation.polepy(p1=Data1, p2=Data2, rlim=150, nbins=150, nhocells=100, blen=1024, dis_f=100)
conda update mkl

What’s causing it, and how can it be resolved in the “the kernel appears to have died. it will restart automatically.“ in the python?

    The cause: I think the problem is a shortage of compute/memory resources while training these large models, and that places like colab have far more bandwidth than your machine.

    The solution: To solve this error, simply run the following command to upgrade the numpy library:

    conda install numpy if you are using anaconda

    or

    pip install -U numpy if not

  2. This problem occurs when I import sklearn before numpy (not certain if you reverse the sequence to fix the problem).

    Later, I was able to resolve the problem by reinstalling numpy.
