Re: [tauruslib-devel] Taurus & data visualization from file

[Carlos M. F. T. <cf...@ce...>]

Hi Łukasz,
The problem is that taurus assumes as default scheme Tango (for backward 
compatibilities reasons), and for  that  you see this error. The 
modelchooser is trying to connect to a Tango DB, to avoid it you have 
two options:

a) Modify in the tauruscustomsetting file the default scheme. e.g. use Eval
b) Give a non tango model name when you call the taurus widget. e.g. eval:1

What are you trying? What scheme are you planning to use?


I hope this help you!

Best,
Carlos
