这个错误是由于你正在尝试对一个二维数组进行三维索引。在这里,你需要检查代码中的索引操作并确保它们与数组的实际形状相匹配。
在这个具体的错误中,你正在尝试将一个新的 8x8 的数组 reshape 成一个 2 维数组,但是你之前已经将 dct_channel 索引为一个 2 维数组。因此,你需要调整 reshape 的维度以匹配 dct_channel 的形状,或者修改切片以匹配你的需求。
你可以尝试修改代码为:
```
dct_channel[8:16, 8:16] = np.tile(alpha * dct[:, :, np.newaxis, :], (1, 1, 1, 1)).reshape((8, 8))
```
这样,你就可以将一个 3 维数组 reshape 成一个 2 维数组,并将其赋值给 dct_channel 的一个子区域。

这是一个 Python 程序运行时出现的错误信息。其中,第一行是命令行窗口中输入的 Python 程序执行命令,指定了 Python 解释器和要执行的 Python 文件的路径。接下来是一个 traceback,它展示了程序运行时的错误信息。在这个例子中,程序在第 73 行尝试将一个字符串转换为浮点数,但该字符串是一个点,无法转换。此外,在 traceback 中还显示了一些在程序结束时出现的异常,这些异常通常与文件操作有关。在这个例子中,程序试图删除一个文件,但该文件正在被另一个程序使用,因此无法删除。最后两行 traceback 是与 lxml 库相关的异常,这些异常可能与程序中使用的 Excel 文件有关。

这个报错是因为在您的代码中使用了`fcntl`模块来进行文件锁定,但是在您的环境中该模块没有`LOCK_EX`属性。这可能是因为您的操作系统不支持`fcntl`模块或者您的Python版本不兼容`fcntl`模块。
您可以尝试使用其他方式来实现文件锁定,例如使用`msvcrt`模块(仅适用于Windows系统)或者使用`fcntl`模块的其他属性(例如`LOCK_SH`、`LOCK_NB`等)。
另外,请确保您的Python版本和操作系统环境与代码中使用的模块和属性兼容。
如果您需要更具体的帮助,请提供您使用的Python版本以及操作系统信息。
