The kernel crash when i import pandas

Hello everybody i am new here and i beginner with python.
This morning i installed keras because i wanted to use LSTM but unfortunately the kernel died.
That is why i removed keras and uninstall and reinstall Visual Studio Code on my MacBookPro.
The problem is now the following : when i import pandas the kernel crashs and it crashs only when i import pandas. I tried to update both pandas and jupyter with pip command but it did not solve my problem. Thank you in advance for your helps
