I had this problem too, maybe related to python 3. I applied this patch:
krig/parallel-ssh@17d96eb

and it seems resolved

For anyone who may run into this issue - I got a very similar message with a TypeError. Searched for a bit but could not find a solution anywhere so I edited my local version of pssh on MacOS Catalina 10.15.5.

In the file psshlib/task.py - line 170 :
change - self.byteswritten = start + os.write(fd, chunk) to self.byteswritten = start + os.write(fd, str.encode(chunk))

This resolved my problem immediately when reading input from a script.
