FileNotFoundError:[Errno 2]尝试导入stockfish引擎时没有此类文件或目录

Question

我正在尝试将Stockfish国际象棋引擎用于一个项目，并尝试导入该引擎（Stockfish.app）。我正在使用以下代码：

import subprocess

engine = subprocess.Popen("/Users/_/Downloads/stockfish.app", universal_newlines=True, stdin=subprocess.PIPE, stdout=subprocess.PIPE,)

但我得到了以下输出：

Traceback (most recent call last):
  File "/Users/_/Documents/Python/AI/Chess/Chess/stockfishAI.py", line 3, in <module>
    engine = subprocess.Popen("/Users/_/Downloads/stockfish.app", universal_newlines=True, stdin=subprocess.PIPE, stdout=subprocess.PIPE,)
  File "/opt/anaconda3/envs/tensor/lib/python3.6/subprocess.py", line 729, in __init__
    restore_signals, start_new_session)
  File "/opt/anaconda3/envs/tensor/lib/python3.6/subprocess.py", line 1364, in _execute_child
    raise child_exception_type(errno_num, err_msg, err_filename)
FileNotFoundError: [Errno 2] No such file or directory: '/Users/_/Downloads/stockfish.app': '/Users/_/Downloads/stockfish.app'

我不知道为什么会发生这种情况，因为我已经准确地复制了目录。 这是目录中的文件

Contents

./Contents:
Info.plist  PkgInfo     _CodeSignature
MacOS       Resources   _MASReceipt

./Contents/MacOS:

我不知道我在Mac上是否与此有关，从我看到的导入stockfish的示例来看，大多数都是在Windows上（导入.exe文件而不是.app） 如果可能的话，请帮助我，因为我对这个错误完全感到困惑
