MacOS 下开启 Metal 会崩溃

Open xp19870106 opened this issue 1 year ago • 4 comments

在void MNNRobustVideoMatting::initialize_interpreter()中，修改代码，设置Metal，如下 MNN::BackendConfig backend_config; backend_config.precision = MNN::BackendConfig::Precision_High; // default Precision_High schedule_config.backendConfig = &backend_config; schedule_config.type = MNN_FORWARD_METAL; schedule_config.backupType = MNN_FORWARD_METAL;

在执行static void test_mnn()的时候，会崩溃 截屏2023-05-12 15 23 48

请问是否我开在MNN Metal的方式不对

那如果想要开启GPU加速，在Mac下目前是用什么方案呢？

mnn调用非cpu后端的时候，需要使用CopyFromHostTensor来进行tensor的拷贝，否则会出现空指针导致crash
