I found the problem. Originally, I was getting errors that were related
to formatting, apparently. It looked fine to me, but because I had
copied it from the web, there were, apparently, hidden characters. In an
effort to get rid of errors, I was eliminating some lines. I finally
added a line,
# -#- coding: utf-8 -*-
near the beginning of the file. This is when I got to where I was with
it seeming to run if I started the command line with python3 but getting
errors if I started with python. I was pretty sure I had all of the
required modules installed.
But then, when instructed to add some lines at the end for debugging, I
found that I had accidentally removed two lines at the end and forgot to
add them back in.
They were:
if __name__=="__main__":
main()
Once I added them, it runs fine whether I say python LED_model_utf8.py
LED_IV.txt or python3 LED_model_utf8.py LED_IV.txt
Thanks to everyone. Sorry for the mistake on my part. I think that if I
had added the # -#- coding: utf-8 -*- right from the start, the problem
never would have happened.

Yes. I'm assuming you just cut n paste the code from the web site but
something could have gone wrong with the formatting and Python is
sensitive to that, so seeing your actual code would be a good idea.
Could you also provide a small set of sample data that fails, maybe
$ head LED_IV.txt > sample.txt
will be enough.
