NameError: name 'arr' is not defined

这个错误是因为你在代码中引用了一个未定义的变量 'arr'。要解决这个问题，你需要确保在引用 'arr' 变量之前先定义它。你可以通过声明变量并给它赋予一个值来定义它，例如：

arr = [1, 2, 3]

或者，如果你只是想检查变量是否已经定义，你可以使用条件语句来避免出现错误。例如：

if 'arr' in locals():
    # 在这里使用 arr 变量
else:
    # 执行其他操作

希望这可以帮助你解决问题！如果你有任何其他问题，请随时提问。

相关问题

NameError: name 'im' is not defined. Did you mean: 'id'?

这个错误提示意味着你在使用变量`im`之前没有定义它。请检查你的代码，确保变量`im`已经被正确地定义和赋值。

例如，如果你的代码类似于以下形式：

im_arr = np.array(im)

im.show()

这里的问题是在使用变量`im`之前没有定义它，可以将其改为以下形式：

im = Image.open('D:/wjd/test.png')
im_arr = np.array(im)

im.show()

注意到现在`im`变量已经被定义和赋值，可以被后面的代码使用。请根据你的具体代码，正确地定义和赋值变量`im`。

Error in setup: "ReferenceError: originColums is not defined" found in

在提供的代码片段中，确实存在一个引用错误：“ReferenceError: originColums is not defined”。此错误发生在尝试使用 `originColums` 变量之前未正确初始化它。具体来说，在 `setup` 函数中，`originColums` 应该被定义并初始化为空数组或所需的初始值。

以下是修正后的代码：
