我正在使用opencv进行服装特征识别.作为第一步,我需要通过从图像中移除面部和手部来分割T恤.任何建议表示赞赏.

我试图在 ubuntu 18.4 (nv-tensorrt-repo-ubuntu1804-cuda10.2-trt7.0.0.11-ga-20191216_1-1_amd64.deb) debian 中安装 tensorRT 7.0。

遵循文档https://docs.nvidia.com/deeplearning/tensorrt/install-guide/index.html#installing-debian。

我在使用 libnvinfer7 时遇到以下错误。在这个星球上寻找这个，无法找到，浪费了我的时间和睡眠。请帮我解决这个问题：

无论如何，都可以将opencv mat对象转换为base64。

我使用下面的URL进行base64编码和解码：

http://www.adp-gmbh.ch/cpp/common/base64.html

下面是代码片段：

const unsigned char * inBuffer = reinterpret_cast（image.data）;

在Windows 10平台上使用mingw32-make命令进行opencv安装,然后可能最终得到以下错误.

Windows版本:10 OpenCv:3.2.0

请建议我安装.

最近我购买了一个预留的实例EC2 t2.medium.

没有选项可以启动和停止,而我的免费装备具有所有功能,包括停止,启动,公共IP等.

请建议我,如何使用和解决保留实例||

在 keras / tensorflow 中训练模型时：

代码片段：

strategy = tf.distribute.experimental.MultiWorkerMirroredStrategy()

我收到以下错误/警告：

Consider either turning off auto-sharding or switching the auto_shard_policy to DATA to shard this dataset. You can do this by creating a new `tf.data.Options()` object then setting `options.experimental_distribute.auto_shard_policy = AutoShardPolicy.DATA` before applying the options object to the dataset via `dataset.with_options(options)`.
