ImportError: No module named *_plugin...

[wwt123-star]

When I run the train.py, it reports the ImportError of *_plugin. I had found the 'build.ninja' generated in the 'bias_act_plugin' and 'upfirdn2d_plugin' files but no 'bias_act.o', 'bias_act.cuda.o' and 'bias_act_plugin.pyd'. How can I solve these issues?
