在 Anaconda 中设置第二个 Python 环境后，导入基本包失败并显示 [WinError 193] %1 is not a valid Win32 application

Question

我想要第二个环境 Python 3.6 和 Tensorflow-GPU v1.15（我的另一个环境是 Python 3.7/TF2.0）。我使用 Anaconda 提示符创建了环境并在那里安装了软件包。当我尝试在 Jupyter Notebook 中导入 pandas 或 numpy 时，它说：

---------------------------------------------------------------------------
OSError                                   Traceback (most recent call last)

     13         missing_dependencies.append(f"{dependency}: {e}")

     27                 DLL_filenames.append(filename)
     28     if len(DLL_filenames) > 1:

C:\ProgramData\Anaconda3\envs\tf1\lib\ctypes\__init__.py in __init__(self, name, mode, handle, use_errno, use_last_error)

    347         if handle is None:
--> 348             self._handle = _dlopen(self._name, mode)
    349         else:
    350             self._handle = handle

OSError: [WinError 193] %1 is not a valid Win32 application

我已经多次尝试卸载/重新安装环境，但均未成功。 github post 对其他人的问题建议确保 PATH 是干净的，但我不确定它是什么意思。我在 Windows 10。
