The url won't load and open, or how to change the jupyter port?

[panwanke]

The url cannot be loaded or opened, often due to port 8888 being occupied.

The solution:

• First, close programs that occupy port 8888, including docker containers that have already been started.
• Another way is to switch ports. For example, use 7777, 8889, 9000 and so on. In this case, the command is docker run -it --rm --cpus=8 -v $(pwd):/home/jovyan/work -p 7777:8888 hcp4715/hddm, while copying the url http://127.0.0.1:8888/tokens=... and copy the url http://127.0.0.1:7777/tokens=...', you need to change the 8888 to the changed port, e.g. http://127.0.0.1:7777/tokens=... `.
