Incubator-superset: load_examples TimeoutError: [Errno 110] Connection timed out

[Gypsying]

Hi friends, i found timeout error while superset load_examples:

My server env :
CentOS 7
Python3.8
Superset 0.30.0
Flask 1.1.1
Werkzeug 0.16.0

superset db upgrade and flask fab create-admin had succeed,
but superset load_examples always failed.

And, i used Python3.6 on CentOS 6 is the same problem...

Any help will be appreciated!!!

I am so sorry, that's my fault:
my server can not resolve the domain: raw.githubusercontent.com

Sorry again ...

This is occurring for me under SQLite as well.. I would need to supply a proxy if a call to raw.githubusercontent.com is necessary and the proxy would have to be open for that domain.

Yeah, that is right;
Or you can find a reachable ip and bind it to the domain in your /etc/hosts

@Gypsying @myzcid would it work if we allowed the examples to be loaded from a local path, instead of a URL? You would download the files somewhere else, and run:

superset load_examples examples-data-master.zip

Yes, that seems like a workable solution.
