浅谈Python traceback的优雅处理

刚接触Python的时候，简单的异常处理已经可以帮助我们解决大多数问题，但是随着逐渐地深入，我们会发现有很多情况下简单的异常处理已经无法解决问题了，如下代码，单纯的打印异常所能提供的信息会非常有限。 def func1(): raise Exception("--func1 exception--") def main(): try: func1() except Exception as e: print e if __name__ == '__main__': main() 执行后输出如下： –func1 exception– 通过示例，我们发现

根据你提供的信息，这是一个 Python 的错误信息，看起来是由于 RandomForestClassifier 模型没有被正确地训练导致的。你需要在使用 predict 函数之前先使用 fit 函数对模型进行训练。你可以检查一下 GetModel.py 文件中的代码，看看是否正确地对模型进行了训练。
