WARNING psi_at_inf_cython module not found

[newton-per-sqm]

When using the actual version 2.0.1 "as is" with sample_pn.py as input file and meff_method = 0 (because aestimo.py is asking for this parameter), then the calculation stops because psi_at_inf_cython module could not be found. In the repository, only a "precompiled" psi_at_inf_cython.pyx file could be found. The same error occurs when probing any sample file with nonparabolic calculations.

Here my run informations:

python main.py

WARNING aestimo logs automatically to aestimo.log in the example's directory.

Could you help me?

If you have problems with cython, the best and the easiest way is not to use it. Because Aestimo is a 1D solver, most calculations can be done in a small amount of time. Therefore, open config.py and change line:

use_cython = True #provides a speed up for aestimo

as

use_cython = False #provides a speed up for aestimo
