ImportError：rasa_nlu.server中没有名为logger的模块

Question

我在尝试运行时遇到错误

python -m rasa_nlu.server -c sample_configs/config_spacy.json

任何人都可以帮忙解决这个问题吗？

代码：

    Traceback (most recent call last):
      File "/usr/lib64/python2.7/runpy.py", line 162, in _run_module_as_main
        "__main__", fname, loader, pkg_name)
      File "/usr/lib64/python2.7/runpy.py", line 72, in _run_code
        exec code in run_globals
