Subject: error running your python example
To: <dmtcp-forum@lists.sourceforge.net>
Hi,
I am trying to run your python example under
dmtcp/contrib/python/hookexample.py
but I saw the following error. I made sure that
I have write/read permission under /tmp/
I even tried using python 2.7 to make sure
that your python programs were written assuming
python 3.
So I cannot think of any other things to try.
Is it because I did not configure anything related to
runtime environment properly? Or you have a version
of dmtcp in which you fixed this error? Please help me!
Thank you very much!
