Examples error

[danyan90]

Hello, I'm a beginner Tango developer, so for better understanding Taurus I had decided to try examples from here I had starter a proposed device server and ctrl-c ctrl-v first code example to pycharm

and this is what I got as a result

[cpascual]

From your screenshot I see some exception related to a tango.gevent which is a PyTango (not taurus) module. I cannot see how you got that, since your screenshot does not sow the stack trace...

In order to be able to help you, can you please copy and paste the actual taurus code that you are running and also the whole console output? (please just copy-paste the text, not an screenshot)

[danyan90]

Yes, of course Code of example:

import sys
from taurus.external.qt import Qt
from taurus.qt.qtgui.application import TaurusApplication

app = TaurusApplication(sys.argv, cmd_line_parser=None,)
panel = Qt.QWidget()
layout = Qt.QHBoxLayout()
panel.setLayout(layout)
from taurus.qt.qtgui.display import TaurusLabel
w = TaurusLabel()
layout.addWidget(w)
w.model = 'sys/taurustest/1/position'

panel.show()
sys.exit(app.exec_())

the result (sorry, I don't know why it's so long, but I think the key moment is at the end)

I just found, the same issue appears when I invoke Taurus from cmd:

MainThread     WARNING  2019-08-30 15:25:20,473 TaurusRootLogger: Cannot add "ql
ogmon" subcommand to taurus. Reason: AttributeError("module 'gevent' has no attr
ibute 'version_info'")

Hola @danyan90 , Seems a problem with your PyTango dependency. How do you install taurus? and (Py)Tango?

[danyan90]

just pip install, and after that i received a fully working system. But I made some doubtful changes at Anaconda environment, maybe that's the cause. Now i'm restoring good configuration with acronis, I hope it would help

[cmft]

This recipe works

[danyan90]

yes, problem solved, thank you every one!

P.S.

This recipe works

yeah, I used this option, sorry
