fileno problem

[Lakshmi Sridhar]

When I run the dae example I get the mwssage

An exception has occurred, use %tb to see the full traceback.

Traceback (most recent call last):

File "C:\Users\LakshmiNSridhar\anaconda3\lib\site-packages\PyDSTool\core\context_managers.py", line 30, in _stdchannel_redirected
oldstdchannel = os.dup(stdchannel.fileno())

File "C:\Users\LakshmiNSridhar\anaconda3\lib\site-packages\ipykernel\iostream.py", line 311, in fileno
raise io.UnsupportedOperation("fileno")

UnsupportedOperation: fileno

During handling of the above exception, another exception occurred:

SystemExit: error: [WinError 2] The system cannot find the file specified
Can anyone help

I think this is fixed in the main branch on github, as per the
discussion in https://github.com/robclewley/pydstool/issues/98. You
should be using the github version of the package for maximal support
on windows.

I re installed the github pydstool
I ran the dae example from the examples directory
I get the messages

I get the fileno problem in other files also
some files are working well
Please tell me how I can fix the fileno problem
I think the error is not with the DAE example file
Because some other files have the same problem

Thanks
