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.但是，这仍然给了我这样的偏斜输出:

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，下一行上都会打印一个新的进度条.通过终端运行脚本时不会发生这种情况.我该如何解决?

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代替tqdm，如这就像将导入更改为:

from tqdm.notebook import tqdm

祝你好运！

编辑:经过测试，看来tqdm在Jupyter笔记本中的文本模式"下实际上可以正常工作.很难说，因为您没有提供最小示例，但是看来您的问题是由每个示例中的打印语句引起的迭代.在每次状态栏更新之间，打印语句都会输出一个数字(〜0.89)，这会使输出混乱.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 ouputting a number (~0.89) in between each status bar update, which is messing up the output. Try removing the print statement.
