The web page is always in the state of "waiting for ··" and cannot show the result

[junkai1120]

When I've configured it, the running code prompts me to open the web page, but when I open page on the Web Server, I get an error message. I tried to add MESA_L_VERSION_OVERRIDE=3.3 in the running line, my page can be opened without error, but the page is still in the state of "waiting for ··". How can I solve this problem?

The print log is as follows:
loading networkG from ./data/PIFu/net_G ...
loading networkC from ./data/PIFu/net_C ...
initialize data streamer ...
