VS Code Interactive 未正确渲染 tqdm.notebook

Question

我曾经在 VS Code Interactive 中使用过，我会得到如下tqdm.auto import tqdm的不错的输出：tqdm

我使用 venv 设置了一个新环境，但现在我失去了它 - 只有文本版本有效：

当我运行这个示例单元时：

from tqdm.auto import tqdm
import time
for i in tqdm(range(10)):
    time.sleep(.1)

我什么也没输出：

我注意到 jupyter 日志中存在一些错误：

Answer 1

我认为你的假设是正确的。我将 ipywidgets 降级到 7.7.1 后，tqdm.notebook 工作正常。
