使用 deeplearning4j 加载模型的时候报了下面这个错。

dyld: lazy symbol binding failed: Symbol not found: ___emutls_get_address
  Referenced from: ~/.javacpp/cache/nd4j-native-1.0.0-beta5-macosx-x86_64.jar/org/nd4j/nativeblas/macosx-x86_64/libnd4jcpu.dylib
  Expected in: /usr/lib/libSystem.B.dylib

在 issues 找到了答案，安装 gcc-8 即可。

brew install gcc@8
