Problem when importing pyds9
Closed this issue · 7 comments
Hello.
When I simply importing pyds9 using python 3.7.11 I got this kind of error.
Traceback (most recent call last):
File "", line 1, in
File "/opt/anaconda3/lib/python3.7/site-packages/pyds9.py", line 800, in
ds9_xpans()
File "/opt/anaconda3/lib/python3.7/site-packages/pyds9.py", line 251, in ds9_xpans
if xpa.xpaaccess(b"xpans", None, 1) is None:
File "/opt/anaconda3/lib/python3.7/site-packages/xpa.py", line 207, in xpaaccess
errmsg += ctypes.string_at(errs[i]).strip() + '\n'
TypeError: can't concat str to bytes
How do you think, what may be a problem?
Thank you.
I am sorry to say that we no longer have a Python expert working on pyds9 to handle questions of this sort. However, the error message you mention does not match the current xpa.py code:
errmsg += ctypes.string_at(errs[i]).strip() + '\n'
should be:
errmsg += to_string(errs[i]) + '\n'
So if you don't have the latest version of pyds9 from github, I would recommend installing it.
Thank you very much @ericmandel,
I will try to update pyds9 version and rerun it.
@ericmandel If its not hard for you, may you update pyds9 version in pypi ?
I used pip install pyds9, but now I am updating from git.
If you may update pyds9 version manual installation for git could be skipped.
I can look into this at some point, but I don't have a lot of time to learn about pypi. This is one of the unfortunate consequences of not having a Python expert to help.

I think this may help you.
I understand that there are pypi install instructions available on the net, but I am trying to say, as gently as possible, that if the community wants a pypi version of pyds9, someone else will have to do it, as I am no longer actively working on DS9 and associated packages. I suppose you might ping the Chandra CIAO software group about supporting pyds9 (they support DS9 itself.) To date, they have been unwilling to put any resources into this package.
Oh, I got.
Okay, Thank you.
