I might be misunderstanding something (probably), but I'm not finding a runtime log or an error message. However, the third candidate in my test run failed and I'm not sure why. That composite is made up of a bunch of p3s and p4s and YAFU factored it in the Colab session when I ran it outside of the script.

sample run of script:
Code:
Installing system packages. . . 
Retrieving GMP-ECM. . . 
Compiling GMP-ECM. . .
Finished installing GMP-ECM. . . 
Retrieving YAFU. . . 
Compiling YAFU. . . 
Finished compiling YAFU. . . 
Starting the factoring of 3 composites. . .  

Composite 1: 8869475002717536050312782604253426183326192888885941092918900891116352039782449522669 <85>
