R中具有Tensorflow和Keras的H5Py问题

编程问答 2022-07-04

问题描述

我在R中总是有相同的错误消息，不知道如何解决。我使用Tensoflow 1.15，Keras 2.2和Python 3.7。

> setwd("C:/Users/PC/Desktop/AI defect/models/")
> model <- load_model_hdf5("my_model_W_AI defect.h5")
Error in load_model_hdf5("my_model_W_AI defect.h5") : 
  The h5py Python package is required to save and load models

代码在这里：
