Spyder Not Launching
I was not able to launch Spyder and Jupyter notebook from anaconda environment (Mac OS).
Following command worked for me:
conda uninstall tornado
conda install tornado==4.5.3
Just uninstall tornado and reinstall it.
Just try this :
- uninstall pyQt using
conda uninstall pyqt
- uninstall sip package
conda uninstall sip
- then install these packages in following order
conda install sip
conda install pyqt
conda upgrade spyder
this worked for me.
For me the outdated library was spyder.kernel. The best solution is to open a new python environment (just input 'py' in command line to build a new environment) and run the following script and it tells you what library is missing or outdated:
from spyder.app import start
start.main()
This solves the problem:
conda upgrade qt
