1. Jupyter Notebook kernel is hung up, you need to restart

Summary of solutions:

1. Uninstall tensorFlow

Reason: The installed TensorFlow version has conflicts with the ENV of Conda. My ENV is available for TensorFlow1.4 installed before the normal situation of Python36. When the business is used in LSTM, it is reinstalled to 2.0. But I can't use it, but the result is still hung up

Test method: Open a new ipynb file. Import Pandas can try whether it can succeed.

At this time, check whether a new package is installed with the Jupyter conflict.

2. Other solutions

2.1 I can't use it here, I also make a reference

import os
os.environ["KMP_DUPLICATE_LIB_OK"]="TRUE"

2.2 Reinstall Jupyter, ipykernel, etc.
