Question

我正在尝试设置一个断点，它抱怨 ValueError: Fatal exception in the data production loop: signal only works in main thread

它来自https://github.com/tensorflow/models/blob/master/official/recommendation/data_pipeline.py

class BaseDataConstructor(threading.Thread):

  ...

class BisectionDataConstructor(BaseDataConstructor):

  def construct_lookup_variables(self):

    import pdb; pdb.set_trace()
    start_time = timeit.default_timer()

   def lookup_negative_items(self, negative_users, **kwargs):

     import pdb; pdb.set_trace()
     output = np.zeros(shape=negative_users.shape, dtype=rconst.ITEM_DTYPE) - 1

https://bugs.python.org/issue13120似乎表明它已修复？（它列出了版本：Python 3.2，Python 3.3，Python 3.4，所以我尝试使用3.4并与3.4兼容）...

我也尝试过 pdb cannot break in another thread?，它也给我带来错误

我在ubuntu上使用python 3.7.2

如何在线程Python中设置断点？
