cmd.stdin.flush（）IOError:[Errno 22]参数无效

Question

基本上，我运行的是运行数小时的大型python脚本

我经常使用Commit对象，比如repo.commit(some_valid_hexsah)

我一次又一次地使用它，其间做了很多事情

不知什么原因，一段时间后，我得到：

File "C:\Users\amirelm\AppData\Local\Continuum\anaconda2\lib\site-packages\gitpython-3.0.1-py2.7.egg\git\repo\base.py", line 482, in commit
    return self.rev_parse(text_type(rev) + "^0")
  File "C:\Users\amirelm\AppData\Local\Continuum\anaconda2\lib\site-packages\gitpython-3.0.1-py2.7.egg\git\repo\fun.py", line 213, in rev_parse
    obj = name_to_object(repo, rev[:start])
  File "C:\Users\amirelm\AppData\Local\Continuum\anaconda2\lib\site-packages\gitpython-3.0.1-py2.7.egg\git\repo\fun.py", line 150, in name_to_object
    return Object.new_from_sha(repo, hex_to_bin(hexsha))
  File "C:\Users\amirelm\AppData\Local\Continuum\anaconda2\lib\site-packages\gitpython-3.0.1-py2.7.egg\git\objects\base.py", line 64, in new_from_sha
    oinfo = repo.odb.info(sha1)
  File "C:\Users\amirelm\AppData\Local\Continuum\anaconda2\lib\site-packages\gitpython-3.0.1-py2.7.egg\git\db.py", line 37, in info
    hexsha, typename, size = self._git.get_object_header(bin_to_hex(sha))
  File "C:\Users\amirelm\AppData\Local\Continuum\anaconda2\lib\site-packages\gitpython-3.0.1-py2.7.egg\git\cmd.py", line 1077, in get_object_header
    return self.__get_object_header(cmd, ref)
  File "C:\Users\amirelm\AppData\Local\Continuum\anaconda2\lib\site-packages\gitpython-3.0.1-py2.7.egg\git\cmd.py", line 1065, in __get_object_header
    cmd.stdin.flush()
IOError: [Errno 22] Invalid argument

我不知道为什么会发生这种情况，如果有人知道如何解释这个错误或经历类似的事情，我将非常感谢您的帮助

谢谢
