我必须对在此仓库中发现的人工智能AlphaZero进行仿真：https://github.com/Zeta36/chess-alpha-zero 因此，首先，我尝试使用Google Colaboratory，但我不知道进行此模拟的正确方法（我只运行Untitled.ipynb），并且收到很多错误
ERROR: Could not open requirements file: [Errno 2] No such file or directory: 'requirements.
这是一个明显的错误，因为Colab不知道谁是requirements.txt以及其他文件，但我不知道如何解决它。有什么想法吗？
所以，然后我以另一种方式尝试了： 1.我下载了项目 2.我按照readme.md上的说明运行了
pip install -r requirements.txt
在项目的根目录中，requirements.txt所在的位置。
我收到此错误：
Brunos-MBP-4:chess-alpha-zero-master Casella$ pip install -r requirements.txt

此错误，我认为是由于我在Mac上安装了python的两个版本，即2.7和3.7.4 无论如何，我继续运行readme.md的命令，然后运行它：
python src/chess_zero/run.py self
我收到了另一个错误：
Brunos-MBP-4:chess-alpha-zero-master Casella$ python src/chess_zero/run.py self
Traceback (most recent call last):
File "src/chess_zero/run.py", line 17, in <module>
mp.set_start_method('spawn')
AttributeError: 'module' object has no attribute 'set_start_method'
最后，我尝试使用修改第一个命令
pip3 install -r requirements.txt
我收到此错误
ERROR: Could not find a version that satisfies the requirement tensorflow-gpu (from -r requirements.txt (line 1)) (from versions: none)
ERROR: No matching distribution found for tensorflow-gpu (from -r requirements.txt (line 1))
有人可以帮助我吗？也欢迎有关如何在Colab上运行github项目的帮助。 预先谢谢你。
