FutureWarning：不推荐使用非元组序列进行多维索引

Question

我收到以下 FutureWarning：

FutureWarning: Using a non-tuple sequence for multidimensional indexing is deprecated; use `arr[tuple(seq)]` instead of `arr[seq]`. In the future this will be interpreted as an array index, `arr[np.array(seq)]`, which will result either in an error or a different result.
  self.commission_matrix[np.meshgrid(indexes, indexes, indexing='ij', sparse=True)] = self.trading_fee[

我该如何制定

    for exc_name in self.exchanges.keys():
        indexes = [index for cur_name, index in self.currency2index.items() if exc_name in cur_name]
        self.commission_matrix[np.meshgrid(indexes, indexes, indexing='ij', sparse=True)] = self.trading_fee[
            exc_name]

这样它就可以避免这个错误？我使用 pychem，没有其他关于此 FutureWarning 的主题可以帮助我。 FutureWarning 不会影响我的结果，但我想知道如何绕过此警告。 非常感谢

Answer 1

我相信这会消除警告：

   for exc_name in self.exchanges.keys():
        indexes = [index for cur_name, index in self.currency2index.items() if exc_name in cur_name]
        self.commission_matrix[tuple(np.meshgrid(indexes, indexes, indexing='ij', sparse=True))] = self.trading_fee[
            exc_name]
