#103497 — Pyraf problem

Dear Sir/Mam, 

I am using python for my astronomy purpose, for that I want to use PyRaf, but strange thing is occurring that pyraf is getting open as a root but out side my root user directory when I am typing pyraf I am getting like; 
No graphics/display possible for this session. 
Tkinter import failed. 
The numpy package is required by PyRAF and was not found. Please visit http://numpy.scipy.org 

I have added bath of pyraf in my bashrc file , I have even downloaded numpy but again it is showing same error. 

Any help will be highly appreciated. 
Thanks and regards,

I am sorry, I don't understand what "getting open as a root" means.

Where are you getting this? Is it a Python traceback? If so, please copy and
paste the entire traceback, starting with the line:

Traceback

and ending with the last of the error message.

Where are you typing pyraf? In the Python interpreter or the operating
system shell? Is the prompt >>> or $ or something else?

Are you using the default Python interactive interpreter, IDLE, or some
third party IDE?

Please explain how you launch Python, e.g.:

"I double-click on the Python icon on the desktop"

"I open a terminal, and enter python at the shell prompt"


Or something else?

What version of Python are you using? What operating system?

What have you added to your bashrc file? Did you add it to the PATH or the
PYTHONPATH?

What happens if you run this at the bash prompt?


python -c "import sys; print(sys.path)"


Do you see the path to pyraf in Python's path? (Python does not use the same
path as bash.)

Hi Sapna, You can't run directly X-window system from root account, SO you are getting Tkinter error. 

You can try to install as follows:

sudo pip install pyraf

But befoore that you also need to install numpy as it is required for pyraf or scipy too.

SO you need to run 
sudo pip install numpy scipy

Above instructions will work only for Python2.X
