安装后识别错误

[lozenyin]

如图所示，本人在一块ARM64的板子上部署了你的代码，但是它并没有正确识别到，请问这种情况需要我怎么修复？

It has to do with the latest version of ncnn. The output is not formatted as before, hence this odd pattern.
Best way to deal with it is replacing ncnn with an older version. You have to re-install ncnn from the beginning.
$ git clone -b 20210720 --depth=1 https://github.com/Tencent/ncnn.git

如果需要使用最新的ncnn的话，代码上需要怎么处理？

使用了git clone -b 20210720 --depth=1 https://github.com/Tencent/ncnn.git
还是没有准确显示

You have to install the older ncnn version according to the guide
Please start at the point where the repo is loaded (see the website)
In case of an 64-OS:

# install ncnn
$ cd ncnn
$ mkdir build
$ cd build
# build 64-bit ncnn
$ cmake -D NCNN_DISABLE_RTTI=OFF -D NCNN_BUILD_TOOLS=ON \
-D CMAKE_TOOLCHAIN_FILE=../toolchains/aarch64-linux-gnu.toolchain.cmake ..
$ make -j4
$ make install
# copy output to dirs
$ sudo mkdir /usr/local/lib/ncnn
$ sudo cp -r install/include/ncnn /usr/local/include/ncnn
$ sudo cp -r install/lib/libncnn.a /usr/local/lib/ncnn/libncnn.a

Or in case of an 32-OS

$ cd ncnn
$ mkdir build
$ cd build
# build 32-bit ncnn
$ cmake -D NCNN_DISABLE_RTTI=OFF \
-D NCNN_BUILD_TOOLS=ON \
-D CMAKE_EXE_LINKER_FLAGS=-ldl \
-D CMAKE_TOOLCHAIN_FILE=../toolchains/pi3.toolchain.cmake ..
$ make -j4
$ make install
# copy output to dirs
$ sudo mkdir /usr/local/lib/ncnn
$ sudo cp -r install/include/ncnn /usr/local/include/ncnn
$ sudo cp -r install/lib/libncnn.a /usr/local/lib/ncnn/libncnn.a

本人已经根据上诉要求进行部署了，情况并没有改变。
