ipython and pyraf?

Adam wrote on Apr 22, 2008

Hi, I use pyraf and ipython for most of my computing needs now, but using pyraf with ipython doesn't work so well. I can load pyraf in ipython using "pyraf --ipython", but once there I can't lpar or epar any tasks.

In [6]: lpar qphot
Warning: Could not find task qphot for lpar

Also, loading pyraf/ipython with "ipython -p pyraf" gives me a number of errors:

Any tips? Google showed no hits except the documentation for pyraf + ipython, so I hope someone else has tried this.

I don't use pyraf myself but if you don't get a quick reply here you might send this to the ST helpdesk as well (help@stsci.edu). From the first error message, are you sure the DIGIPHOT and APPHOT packages are loaded?

Thanks Mike,
I'm not sure the packages are loaded, but I'm sure I've loaded them. ipython pyraf will happily load packages and run them: I was able to run qphot even though I couldn't epar/lpar it.
I also tried 'lpar epar' and 'lpar imcopy' and 'epar ...', they didn't work.

I'll drop STSCI an e-mail too. Thanks.
