Use PdfMerger instead.

这是一个PyPDF2库的警告信息，指出PdfFileMerger已被弃用，并在PyPDF2 3.0.0版本中移除，建议使用PdfMerger替代。因此，在你的代码中，可以将PdfFileMerger改为PdfMerger来避免这个警告。

修改后的代码如下：

from PyPDF2 import PdfFileReader, PdfMerger

# 将两个pdf文件合并成一个
def merge_pdfs(file1, file2, output):
    merger = PdfMerger()
    with open(file1, 'rb') as f1, open(file2, 'rb') as f2:
        pdf1 = PdfFileReader(f1)
        pdf2 = PdfFileReader(f2)
        merger.append(pdf1)
        merger.append(pdf2)
    with open(output, 'wb') as out:
        merger.write(out)

# 调用函数将两个pdf文件合并成一个
file1 = '照片.pdf'
file2 = '11.pdf'
output = 'merged.pdf'
merge_pdfs(file1, file2, output)

这样就可以避免上述警告信息。

这是一个 Python 的 Traceback，看起来是在运行一个名为 "pointcloud_to_scene.py" 的文件时出现了错误。错误的具体信息是 "cannot import name 'escape' from 'jinja2'"，这意味着 Python 找不到名为 "escape" 的函数，这个函数来自于名为 "jinja2" 的模块。你可以尝试检查你的 Python 环境中是否安装了 "jinja2" 模块，并且版本是否正确。如果你没有安装 "jinja2" 模块，你可以使用 pip 命令安装。

这是一个错误提示，指出在导入模块时出错了。具体来说，这是在导入 Flask 模块时出现了错误，因为 Flask 模块依赖于 Jinja2 模块，但是导入 Jinja2 模块时出错了。该错误消息指出，Jinja2 模块中缺少名为 'escape' 的属性。这可能是由于版本不兼容或安装不完整等原因引起的。您可以尝试重新安装 Jinja2 模块，或者检查您的 Python 环境中是否存在其他版本的 Jinja2 模块。
