Using pyraf across environments: Unresponsive icfit window in identify

[Vital-Fernandez]

I have installed iraf/pyraf with the astroconda python 2.7 conda environment.

Pyraf works well within this environment but I have been searching ways to run pyraf tasks with my own scripts in supported python versions.

I have been succesfull launching pyraf tasks in a python 3.7 using the subprocess library and activating the pyraf environement. I am using ubuntu 20.04 and the code looks something like:

bash_command = "bash -c 'source /home/user/anaconda3/bin/activate && conda activate iraf27 && python RunIraf_task.py task_conf_file.txt /home/user/data/folder/ && conda deactivate'"

p1 = subprocess.run(bash_command, shell=True, capture_output=True)

This works very well for most tasks and it makes possible to keep the pyraf installation isolated. However, I noticed an issue in the identify task: While trying to define a line (m key) the plot window becomes kind of frozen. This does not happen in the fit window (f key) which works as expected.

I guess this is because the task wants to display some information in the terminal or is waiting for some user input. I wonder if anyone has a workaround this issue or if they would suggest some strategy to run pyraf accross python environments.

Thank you for your work

Did you try to use the Pyraf that comes with Ubuntu?

$ sudo apt install python3-pyraf

The problem you will have with your problem is that the development of the Astroconda IRAF/PyRAF packages is basically finished; there will almost probably no new releases or bugfixes.
