Sorry it took a while to respond to this. I believe you'll just have to include
the gil before each print statement. At the beginning of the
enet_coordinate_descent algorithm you'll see a statement "with nogil:" which
releases the python gil increasing the c performance. I suppose you could just
remove the "with nogil:" though I'm not sure what kind of effect that would
have. Is there a reason you want to use the gil for the entire algorithm apart
from convenience?

with gil: print("something with gil")
That seems to work. What doesn't is to get the GIL for the whole algorithm (it
compiles without errors but messes up the algorithm)
Un saludo,

Hey Alberto,
Try
with gil: print("something with gil")
Let me know if that works

Subject: [Scikit-learn-general] Print coordinate descent coefficients at
each iteration
Hi,
I would like to print the coordinate descent coefficients at each iteration. So
far I've identified the code and variable I want to print. In particular I want
to print the variable w in function enet_coordinate_descent from cd_fast.pyx.
The problem is I do not have any previous experience with Cython and, as far as
I've read, you can not simply put a print or a write statement because you run
into problems with the GIL. Anyone has any pointers on how to solve this
problem? Thank you very much in advance.
