I was asking SAGE to do a calculation that I knew was probably laborious -- I had a plane curve (over Q) and I wanted its genus. I defined it with C=Curve(equation_in_two_variables) and then typed
C.genus() after a while (I was in the notebook) I just got the mysterious error message: delaybeforesend: 0 when I expanded it, at the end there was a lot of stuff, but the relevant line was pexpect.TIMEOUT: Timeout exceeded in read_nonblocking(). <pexpect.spawn instance at 0xa1c170c> command: /u/victor/sage/local/bin/Singular So, there are two questions: a) is it possible to give a more informative error message. It seems obvious that singular just took too long in getting back to sage. b) is it possible to give a longer timeout (if I really want the answer)?
