Problem on running the example of galactic lensing

[swaraj3026]

Shows this error in all the galactic lensing examples -
"The kernel for file_name.ipynb appears to have died. It will restart automatically."
For this code which is in the example section. Except this, all examples are running smoothly

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
%matplotlib inline

import healpy
import matplotlib.pyplot as plt

#stack all maps
crMap = np.zeros(49152)
for pid in M.getParticleIds():
energies = M.getEnergies(int(pid))
for i, energy in enumerate(energies):
crMap += M.getMap(int(pid), energy * crpropa.eV )

#plot maps using healpy
healpy.mollview(map=crMap, title='Unlensed')
plt.savefig('unlensed_map.png')

Hi @swaraj3026
This is unfortunately a known issue and several attempts to fix the bug did work yet. If you rely on the lenses, you probably best go back to an earlier python version (I think 3.6) and a Linux machine. There the tests for the lenses were running the longest.
Otherwise we are working on a new implementation of the lenses but the project has no scheduled time frame.
