Hi Carlos,
I just encountered the same error on Spyder 3.0.2 :(
Win10 64bit, an environment of Miniconda 2 with Python 2.7.13.
The error:
Traceback (most recent call last):
File
"C:\Miniconda2\envs\default_py2\lib\site-packages\qtconsole\base_frontend_mixin.py"
, line 163, in _dispatch
handler(msg)
File
"C:\Miniconda2\envs\default_py2\lib\site-packages\spyder\widgets\ipythonconsole\namespacebrowser.py"
, line 189, in _handle_execute_reply
self.handle_exec_method(msg)
File
"C:\Miniconda2\envs\default_py2\lib\site-packages\spyder\widgets\ipythonconsole\shell.py"
, line 242, in handle_exec_method
properties = ast.literal_eval(data['text/plain'])
KeyError: 'text/plain'
>From spyder\widgets\ipythonconsole\shell.py, lines 234-249:
data = reply.get('data')
if 'get_namespace_view' in method:
if data is not None and 'text/plain' in data:
view = ast.literal_eval(data['text/plain'])
self.sig_namespace_view.emit(view)
else:
view = None
elif 'get_var_properties' in method:
properties = ast.literal_eval(data['text/plain'])
self.sig_var_properties.emit(properties)
else:
if data is not None:
self._kernel_reply = ast.literal_eval(data['text/plain'])
else:
self._kernel_reply = None
self.sig_got_reply.emit()
It seems the current solution works only for the first condition (if
'get_namespace_view' in method) but not for the others (elif
'get_var_properties' in method, else).
I hope this will help somehow, please tell me if you need more info.
Thanks,
Shaked
