Jupyter Notebook 中的 tqdm 反复打印新的进度条 [英] tqdm in Jupyter Notebook prints new progress bars repeatedly

问题描述

我正在使用 tqdm 在我在 Jupyter 笔记本中运行的脚本中打印进度.我正在通过 tqdm.write() 将所有消息打印到控制台.然而，这仍然给了我一个像这样的倾斜输出:

I am using tqdm to print progress in a script I'm running in a Jupyter notebook. I am printing all messages to the console via tqdm.write(). However, this still gives me a skewed output like so:

也就是说，每次必须打印新行时，下一行都会打印一个新的进度条.当我通过终端运行脚本时不会发生这种情况.我该如何解决这个问题?

That is, each time a new line has to be printed, a new progress bar is printed on the next line. This does not happen when I run the script via terminal. How can I solve this?

推荐答案

尝试使用 tqdm.notebook.tqdm 而不是 tqdm，如这里.

Try using tqdm.notebook.tqdm instead of tqdm, as outlined here.

这可能就像将导入更改为:

This could be as simple as changing your import to:

从 tqdm.notebook 导入 tqdm

祝你好运！

经过测试，似乎 tqdm 在 Jupyter 笔记本中的文本模式"中实际上运行良好.很难说，因为您没有提供最小示例，但看起来您的问题是由每个打印语句引起的迭代.打印语句在每次状态栏更新之间输出一个数字 (~0.89)，这会弄乱输出.尝试删除打印语句.

After testing, it seems that tqdm actually works fine in 'text mode' in Jupyter notebook. It's hard to tell because you haven't provided a minimal example, but it looks like your problem is caused by a print statement in each iteration. The print statement is outputting a number (~0.89) in between each status bar update, which is messing up the output. Try removing the print statement.
