#2363 — PyVISA

I have unpacked the PyVISA files into the Python/lib/site-packages dir
and from the IDLE GUI I get and error

import visa

Traceback (most recent call last):
  File "<pyshell#25>", line 1, in <module>
    import visa
ImportError: No module named visa



There must be more to just putting the files in the correct directory.
Need help configuring PyVISA to work.
My ultimate goal is to control electronic instruments with Python
through visa.

Yes, there is more:

- DON'T unpack the files into any site-packages folder. If you already
  have done it, remove them.
- Unpack the PyVISA archive to any other folder.
- On the command line, change into the PyVISA folder. There you should
  find - among others - the two files setup.py and setup.cfg (at least
  if you use PyVISA-1.3.tar.gz).
- Now, it depends on what variant of python you use and want to install
  PyVISA for and on the configuration of your PYTHONPATH rsp. sys.path
  and the folders they point to.
  You can simply try: 'sudo python ./setup install'
  If you are lucky, that's it. If not, you have to decide, where the
  installation script has to put the files to. For example, for my
  python 2.6, I chose
  '/Library/Frameworks/Python.framework/Versions/2.6/'. In this path,
  there is a folder 'lib/site-packages', which is pointed to by
  sys.path, and where .pth files are evaluated.
- Edit the file setup.cfg. Near the end, in section '[install]', you will
  find the line 'prefix=/usr'. Replace the '/usr' by your chosen path.
- Save the file and retry the install (see above).



Best regards,

  Günther

Well, ok, I'll try some of that. But I am running window 7, not Linux.
The "sudo" command sounds like Linux.

I did a little writeup for setting PyVISA up in Windows. It's not exactly polished, but it can get you through the difficult bits. If you need any additional help, leave comments/questions on my blog.
