WARNING: Retrying (Retry(total=4, connect=None, read=None, redirect=None, status=None)) after connection broken by 'ReadTimeoutError("HTTPSConnectionPool(host='pypi.org', port=443): Read timed out. (read timeout=15)")': /simple/htmlsession/ ERROR: Could not find a version that satisfies the requirement htmlsession (from versions: no ne) ERROR: No matching distribution found for htmlsession

这个错误提示表示在 PyPI（Python Package Index，Python 包索引）中没有找到名为 `htmlsession` 的库，因此安装失败。你可能需要检查你输入的包名是否正确，或者尝试使用其他替代方案。

如果你想要使用 `HTMLSession` 类，可以按照以下步骤安装 `requests_html` 库：

1. 打开终端或命令行窗口。
2. 输入以下命令安装 `requests_html` 库：`pip install requests-html`。
3. 等待安装完成后，在 Python 代码中使用 `from requests_html import HTMLSession` 导入 `HTMLSession` 类即可。

如果你仍然遇到问题，请尝试更新你的 pip 版本，使用以下命令：`pip install --upgrade pip`。

这个错误提示表明你的Python解释器无法下载selenium库。你可以尝试以下方法来解决这个问题：

1. 确保你的网络连接正常，或者尝试更换网络环境。
2. 确保你的Python版本正确，并且使用pip来安装selenium库。你可以在终端或命令行中执行以下命令：`pip install selenium`
3. 如果你使用的是Python虚拟环境，请确保已经在正确的虚拟环境中执行安装命令。
4. 如果上述方法都不能解决问题，你可以尝试手动下载selenium库，并将其解压到Python解释器的site-packages目录中。你可以在https://pypi.org/project/selenium/ 页面中找到selenium库的下载链接。

这个错误提示表明 pip 无法连接到代理，无法从 PyPI（Python Package Index）上下载 tensorflow 包。你需要检查一下网络连接是否正常，或者更换一个可用的代理。你可以尝试使用国内的镜像源，如清华大学的 pip 镜像源，命令为：`pip install -i https://pypi.tuna.tsinghua.edu.cn/simple tensorflow`。
