DepreciationWarning: 'input_splitter' is deprecated since IPython 7.0 prefer 'input_transformer_manager'

[Durksz]

I installed Pythonocc 0.18.2 on my windows 7 64bit machine.

When i try to run the following code:
from OCC.wxDisplay import wxViewer3D

I get the following warning:
C:\ProgramData\Miniconda3\lib\site-packages\ipykernel\ipkernel.py:448: DeprecationWarning: input_splitter is deprecated since IPython 7.0, prefer input_transformer_manager.
status, indent_spaces = self.shell.input_splitter.check_complete(code)

The message is pretty clear: ipykernel ( != pythonocc ) has a deprecation

from OCC.wxDisplay import wxViewer3D

Yep, it would be particular to have ipykernel msg's when importing the wx backend.
So this is coming from somewhere else in your program p'bably

[Durksz]

Hmm, Your right. Sorry my fault.

Something that certainly comes from wxPython itself, or ipython, or both. According to spyder-ide/spyder#8103, you should try to downgrade to ipython6. @Durksz Can you please report any success/failure so that we can safely close this issue.

I've downgraded PythonOCC to 0.18.1 and the error still occurs, definately not an PythonOCC problem. Have not found the specific package (and its version) yet that causes the problem.

[Durksz]

After upgrading all the packages using "conda update --all" (causing PythonOCC to downgrade to 0.17.3, so I followed by the command "conda install PythonOCC-Core==0.18.2") the problem does not occur anymore.

[tpaviot]

ok @Durksz I suggest you close this issue

[Durksz]

Closed #642

[PCdurham]

I updated conda yesterday and with Spyder 3.3.6 this issue still occurs. It's quite serious since the iPython console is rendered useless.

In my case, calling warnings.simplefilter('always') is what causes the warning to start appearing. Note that this line can be found multiple times in OCC.

To reproduce the following example, each input must be copy/pasted into the console and executed one at a time:

In [1]: import warnings

In [2]: 2+2 # no warning message
Out[2]: 4

In [3]: warnings.simplefilter('always')

In [4]: 2+2 # displays warning message
/Users/wrespino/anaconda3/lib/python3.6/site-packages/ipykernel/ipkernel.py:454: DeprecationWarning: `input_splitter` is deprecated since IPython 7.0, prefer `input_transformer_manager`.
  status, indent_spaces = self.shell.input_splitter.check_complete(code)
Out[4]: 4

In [5]: warnings.filters.pop(0) # remove ('always', None, Warning, None, 0) from start of warnings.filters
/Users/wrespino/anaconda3/lib/python3.6/site-packages/ipykernel/ipkernel.py:454: DeprecationWarning: `input_splitter` is deprecated since IPython 7.0, prefer `input_transformer_manager`.
  status, indent_spaces = self.shell.input_splitter.check_complete(code)
Out[5]: ('always', None, Warning, None, 0)

In [6]: 2+2 # no warning message
Out[6]: 4

My setup:
Spyder 4.1.0 | IPython 7.13.0 | Python 3.6.8 64-bit | Qt 5.9.6 | PyQt5 5.9.2 | Darwin 18.7.0
