Question

使用GraalVM从Java春季启动中调用python方法，简单的def起作用了，但是无法检测到另一个文件的导入def。收到错误消息“ 嵌套的异常是org.graalvm.polyglot.PolyglotException：ModuleNotFoundError：没有名为'train '的模块”“

#python code file 1   
from file2 import train
def training(videoFileName,userId):
    k = train(videoFileName,userId)
    return (flag)


#python code file 2 
import cv2
def train(videoFileName,userId):
    # some code 
    # *****************
    return (true)

#Java spring boot code
@Bean
public Context cittaFacePython() throws IOException {
    Context ctx = Context.newBuilder("python").allowAllAccess(true).build();
    File file = new File(pythonProperties.getFile());
    Source source = Source.newBuilder("python", file).build();
    ctx.eval(source);
    return ctx;
}

Value value = cittaFacePython.eval("python", "training('" + videoFileName + "'," + userId + ")");
        System.out.println("+++++++++++++++++++" + value.asString());

原因：org.graalvm.polyglot.PolyglotException：ModuleNotFoundError：没有名为“ train”的模块
