When using jupyter notebook to write code and encounter print without output results , as shown in the following figure
Don't panic, this is not a code error, but the IOPub data rate is limited, that is, jupyter limits the output
Solution
1. cmd opens the command line window, enter jupyter notebook --generate-config (there is a space after the notebook)
If this happens, instead enter jupyter notebook --generate-config in Anaconda Prompt
2. The configuration file path of jupyter appears, do not enter, just follow this path to find the jupyter_notebook_config.py file
3. Open the file with notepad or python, ctrl+F to open the search window, enter iopub_data_rate_limit
Find a specific line, uncomment it, add a lot of 0's
4. Restart the jupyter notebook, the display is normal
