MPP0527.py:700: UserWarning: Matplotlib is currently using agg, which is a non-GUI backend, so cannot show the figure.，这个警告怎么处理？

这个警告表示 Matplotlib 正在使用 agg 后端，该后端不支持图形界面的显示，因此无法显示图形。要解决该问题，可以使用以下两种方法之一：

1. 使用 Matplotlib 的其他后端，例如 TkAgg 或 Qt5Agg，在代码中添加以下行即可：

import matplotlib
matplotlib.use('TkAgg') # 或者 Qt5Agg

2. 将 Matplotlib 的后端设置为交互式后端，在代码中添加以下行即可：

import matplotlib.pyplot as plt
plt.ion() # 将 Matplotlib 设置为交互式后端

这两种方法都可以解决该警告。

error while loading shared libraries: /athrun/lib/librockchip_mpp.so.1: file too short

The error message "error while loading shared libraries: /athrun/lib/librockchip_mpp.so.1: file too short" typically indicates that the shared library file `librockchip_mpp.so.1` is corrupted or incomplete. This can occur due to various reasons, such as incomplete installation or file corruption.

To resolve this issue, you can try the following steps:

1. First, check if the library file exists in the specified path (`/athrun/lib/`). You can use the `ls` command to verify its presence:

   ls /athrun/lib/librockchip_mpp.so.1

2. If the file exists, try reinstalling the library by downloading it from a reliable source or reinstalling the package it belongs to. Make sure to download or install the complete and uncorrupted file.

3. If the file doesn't exist or reinstalling doesn't solve the issue, it's possible that there was an error during the installation or an issue with the file itself. In such cases, you may need to contact the software or library provider for further assistance.

Additionally, you can also check if there are any dependencies required by the library and make sure they are installed correctly. The `ldd` command can help you identify the dependencies:

ldd /athrun/lib/librockchip_mpp.so.1

Make sure all the listed dependencies are present and properly installed on your system.

If the issue persists or you need further assistance, please provide more details about your system, the software or package you are working with, and any additional error messages you encounter.

../configs/mpp_ssg.mk: 没有那个文件或目录 执行makefile报的错，该怎么修改

当执行 Makefile 时出现 "../configs/mpp_ssg.mk: 没有那个文件或目录" 错误，这表示 Makefile 中引用的 "../configs/mpp_ssg.mk" 文件不存在。

要解决这个问题，您可以采取以下措施之一：

1. 检查路径：确保 "../configs/mpp_ssg.mk" 文件的路径是正确的。您可以使用 `ls` 命令来验证文件是否存在于指定的路径中。

2. 修改 Makefile：如果确保文件存在于正确的路径下，您可以打开 Makefile 并找到包含 "../configs/mpp_ssg.mk" 的行。检查路径是否正确，并确保文件名拼写准确。

3. 检查依赖关系：如果 "../configs/mpp_ssg.mk" 是另一个 Makefile 文件的依赖项，您需要确保该文件在执行当前 Makefile 之前已经构建或准备好。

4. 检查环境变量：有时候 Makefile 中的路径可能依赖于环境变量。确保相关的环境变量设置正确，并且与所需的路径匹配。

根据具体情况调整以上措施可以帮助您解决该错误。
