notebook: Strange problem with jupyter qtconsole.
Hello.
I have some problem with jupyter Qtconsole. I am using WinPython 3.4 64bit for some scientific calculation. Today something strange happens. When I open Spyder IPython console does not work.
I try to install new version of WinPython 3.5 with same result. I try to start command jupyter qtconsole
and get empty console window with no prompt of ipython like show on attachment.
When I try start jupyter console everything is working fine also jupyter notebook is working. Qt Demo program from WinPython also working. I try to run jupyter qtconsole --debug and get following output:
C:\Programs\WinPython\python-3.5.1.amd64>jupyter qtconsole --debug [JupyterQtConsoleApp] Config changed: [JupyterQtConsoleApp] {‘JupyterQtConsoleApp’: {‘log_level’: 10}} [JupyterQtConsoleApp] Searching [‘C:\Programs\WinPython\python-3.5.1.amd64’, ‘C:\Programs\WinPython\settings.jupyter’, ‘C:\Programs\WinPython\python-3.5.1.amd64\etc\jupyter’, ‘C:\Program Data\jupyter’] for config files [JupyterQtConsoleApp] Looking for jupyter_config in C:\ProgramData\jupyter [JupyterQtConsoleApp] Looking for jupyter_config in C:\Programs\WinPython\python-3.5.1.amd64\etc\jupyter [JupyterQtConsoleApp] Looking for jupyter_config in C:\Programs\WinPython\settings.jupyter [JupyterQtConsoleApp] Looking for jupyter_config in C:\Programs\WinPython\python-3.5.1.amd64 [JupyterQtConsoleApp] Looking for jupyter_qtconsole_config in C:\ProgramData\jupyter [JupyterQtConsoleApp] Looking for jupyter_qtconsole_config in C:\Programs\WinPython\python-3.5.1.amd64\etc\jupyter [JupyterQtConsoleApp] Looking for jupyter_qtconsole_config in C:\Programs\WinPython\settings.jupyter [JupyterQtConsoleApp] Looking for jupyter_qtconsole_config in C:\Programs\WinPython\python-3.5.1.amd64 [JupyterQtConsoleApp] Config changed: [JupyterQtConsoleApp] {‘JupyterQtConsoleApp’: {‘log_level’: 10}} [JupyterQtConsoleApp] Connection File not found: C:\Programs\WinPython\settings\runtime\kernel-1324.json [JupyterQtConsoleApp] Native kernel (python3) available from C:\Programs\WinPython\python-3.5.1.amd64\lib\site-packages\ipykernel\resources [JupyterQtConsoleApp] Starting kernel: [‘C:\Programs\WinPython\python-3.5.1.amd64\python.exe’, ‘-m’, ‘ipykernel’, ‘-f’, ‘C:\Programs\WinPython\settings\runtime\kernel-1324.json’] [JupyterQtConsoleApp] Connecting to: tcp://127.0.0.1:1892 [JupyterQtConsoleApp] connecting shell channel to tcp://127.0.0.1:1889 [JupyterQtConsoleApp] Connecting to: tcp://127.0.0.1:1889 [JupyterQtConsoleApp] connecting iopub channel to tcp://127.0.0.1:1890 [JupyterQtConsoleApp] Connecting to: tcp://127.0.0.1:1890 [JupyterQtConsoleApp] connecting stdin channel to tcp://127.0.0.1:1891 [JupyterQtConsoleApp] Connecting to: tcp://127.0.0.1:1891 [JupyterQtConsoleApp] connecting heartbeat channel to tcp://127.0.0.1:1893
I check on different computer and get similar output but qtconsole is working fine.
Can you suggest any solutions for this problem?

I see the blank screen, but if I hit enter, it shows me a prompt. I’m not currently sure what’s going wrong, but that at least seems easier than downgrading stuff.
This will be fixed in the next release of qtconsole (version 4.3).
OK I get it. The problem is because of Anaconda. I was typing %qtconsole in jupyter notebook that had python kernel that was not activated. I changed python kernel in jupyter notebook to ‘Python [conda root]’ and qtconsole is squiky fresh and working.
