Installing OpenCV2 for Python

The way to install OpenCV is opkg update && opkg install opencv. That works, but it doesn't seem to include Python binding. How do you install the cv2 package?

"libgcc_s.so.1: file not recognized: File format not recognized" on Ubuntu 20.04

Tried to get the hello_world example to compile on Ubuntu 20.04 (x64) but am getting an error at linking time:
/usr/lib/libgcc_s.so.1: file not recognized: File format not recognized

On closer inspection it happens with every example. My libgcc-s1 version is 10.2.0

Thanks for looking into this!

你好，下载的toolchain-sunxi-musl-pack-2021-01-09.tar.xz里面的linux/version.h里面的version code跟https://api.dl.sipeed.com/shareURL/MaixII/SDK/release 下载的image使用的linux内核版本不一致，toolchain-sunxi-musl-pack-2021-01-09.tar.xz的linux版本低于4.8.0导致我一些软件编译不了

SDK中，axpi需要的libax_npu_cv_kit.so等库在哪里下载呢？

在交叉编译example/axpi下的例子时，缺少很多相关函数的定义，应该是在libax_npu_cv_kit.so等库中。这些库我在axpi的板子上能够找到，但是SDK中似乎没有。我只能从axpi板上拷贝过来吗？

main.c:(.text+0x70): undefined reference to `libmaix_nn_module_init'

I'm compiling /libmaix/examples/nn_pose/ Times this error.

How to modify it?

支持h264/265 encode&decode吗

如题，下载了该工程并没发现h264,265的相关SDK功能，只是mjpeg的话网络传输不了1080p的

ISP errors occurring when set input_size with 416*416 in C++ code

Hello! I follow these instructions in dianjixz/v831_yolo and set both train_size and val_size parameters are 416*416 and to train in my computer, and then I convert my mode into onnx mode and ncnn mode, finally I upload them on the toolbox website to convert into awnn mode.
`

if args.multi_scale:
    print('use the multi-scale trick ...')
    train_size = [640, 640]
    val_size = [416, 416]
else:
    train_size = [416, 416]
    val_size = [416, 416]

I am sure that my training and modes are correct, and I modify below these codes and replace my trained mode, I try my best to run many time on V831 with C++ code, however there are some ISP errors occurring and the screen is full green(I upload the yolov2_camera_error.log and you can check it), how do I sovle it?
However I follow the same setting in Python code, it can run normally with low frame rate. Does the V831 not support the input_size with 416*416 in C++ code? I am urgent to apply these into my projects recently, thank you for your help!

Provide source

Why are you not providing the source code for libmaix SO files? I can understand that the SDK is private, but the value of the whole project seem very limited without the source code for the central library.

r329中libaipudrv.so 和libaipudrv.so.4能否升级到zhouyi compass sdk v2.1 最新版本

r329中libaipudrv.so 和libaipudrv.so.4 是否是单独在Zhouyi_Compass\AI610-SDK-r0p0-00eac0\AI610-SDK-1012-r0p0-eac0\Linux-driver下面编译出来的还是有什么依赖？我这遇到zhouyi compass sdk v2.0 对有些算子不支持，最新版可以支持。

Allwinner V831 SDK

Can you please put the Allwinner V831 SDK up somewhere? We have a bunch of code running on the Allwinner V536 using their MPP library to implement WebRTC. I think this WebRTC code should easily port on to the V831 but I can't find the SDK anywhere to try it out.

No need for a giant 10GB tar file. Have a look at how Lindenis put the V536 SDK up on Github.
http://wiki.lindeni.org/index.php/Lindenis_V536#Downloading

The V831 SDK is supposed to be derived from the V536 one so I am expecting it to be 98% identical.

BTW: we just started porting the WebRTC to the RV1109/26. We have the Rockchip SDK and it does not look like much trouble to do the port. We are using the tiny Firefly RV1109 module right now. We just ordered 10 more full sized dev boards from another vendor, they aren't here yet.

Firefly used the same repo system to put the RV1109 SDK up...

retinaface example run failed

u-boot SPL source or config options

I'm naively imagining that the tiny SPL part (49KB) isn't proprietary. Especially considering that several Allwinner SoCs are mainlined. Can you provide the source for it, or at least the .config file so there is a chance of reproducing it?

While you're at it how about the build output for the Linux kernel. It would be nice to know what the device support it has.

libmaix_nn.so: undefined reference to `retinaface_get_priorboxes'

我在自己配置工具链路径，自己编写CMakeLists进行编译时，添加了libmaix/components/libmaix/lib/arch/v831下的libmaix_nn.so文件。在编译一个简单的hello world时，出现了如下错误：
libmaix_nn.so: undefined reference to 'retinaface_get_priorboxes'
libmaix_nn.so: undefined reference to 'retinaface_decode'
根据libmaix/components/libmaix下的CMakeLists，我注意到可能需要liblibmaix.a这个静态库，但我没有在sdk中找到它。
最后在libmaix/components/libmaix/src/decoder下找到了decoder_retinaface.c文件，将其添加到项目中一起编译解决了上述问题，但我很疑惑为什么没有将decoder_retinaface.c编译为库，而是作为一个源文件，这样在配置自己的编译环境时很容易忽略掉还缺少这个文件。
