How do I know what version of CIAO is installed?
The ciaover command displays the installed CIAO packages and the format indicates whether CIAO was installed with ciao-install or conda.
Example: conda
The installed CIAO packages and their version are listed
unix% ciaover -v The current environment is configured for: CIAO : CIAO 4.16.0 Tuesday, December 05, 2023 Contrib : Package release 0 Tuesday, November 28, 2023 bindir : /soft/ciao-4.16/bin Python path : /soft/ciao-4.16/bin CALDB : 4.11.0 System information: Linux is.awesome.edu 4.18.0-477.13.1.el8_8.x86_64 #1 SMP Thu May 18 10:27:05 EDT 2023 x86_64 x86_64 x86_64 GNU/Linux
Example: ciao-install
The ciaover output looks like
unix% ciaover CIAO 4.16.0 Tuesday, December 05, 2023 bindir : /soft/ciao-4.16/bin CALDB : 4.11.0
and it has a verbose form which lists the component packages too, as well as information on the machine:
unix% ciaover -v The current environment is configured for: CIAO : CIAO 4.16.0 Tuesday, December 05, 2023 Contrib : Package release 0 Tuesday, November 28, 2023 bindir : /soft/ciao-4.16/bin Python path : /soft/ciao-4.16/bin CALDB : 4.11.0 System information: Linux is.awesome.edu 4.18.0-477.13.1.el8_8.x86_64 #1 SMP Thu May 18 10:27:05 EDT 2023 x86_64 x86_64 x86_64 GNU/Linux
Please include the output of ciaover -v as text (not as a screen shot of your terminal) when reporting a problem or question to the CXC Helpdesk, as this information can often help us pinpoint the problem (and will be one of the first things we ask you for in response to your question).
