1、报错日志1
java.lang.NoSuchMethodError: java.nio.file.Files.readString(Ljava/nio/file/Path;)Ljava/lang/String; at org.pytorch.serve.util.ConfigManager.readFile(ConfigManager.java:235) at org.pytorch.serve.util.ConfigManager.(ConfigManager.java:139) at org.pytorch.serve.util.ConfigManager.init(ConfigManager.java:285) at org.pytorch.serve.ModelServer.main(ModelServer.java:83)
解决方案
jdk的版本不对，安装jdk 11
