Python Can'；不要使用progressbar33软件包

我想显示下载进度，但无法按预期运行， 这是我的密码

import requests
from progressbar import Bar, ETA, FileTransferSpeed, ProgressBar


link = video_mp4_link
file_name = "download.mp4"

with open(file_name, "wb") as f:
    print("Downloading {}".format(file_name))
    response = requests.get(link, stream=True)
    total_length = int(response.headers.get('content-length'))

    widgets = ['[Downlaoding] ', Percentage(), ' ', Bar(),
            ' ', ETA(), ' ', FileTransferSpeed()]

    pbar = ProgressBar(widgets=widgets, maxval=total_length).start()
    for data in response.iter_content(chunk_size=4096):
        f.write(data)
        done = int(os.path.getsize('Tree_Scraper.py'))
        pbar.update(done)
    pbar.finish()

下载文件时，会显示如下进度：

[下载]0%|预计到达时间：35天，3:50:24 600 B/s

进度条卡在0%，预计到达时间为35~100天，下载速度为 B/s

下载文件后，进度如下：
