R中的load_model_hdf5“ my_model_W18_2c2.h5”错误

问题描述

当我尝试用R加载模型时出现以下错误。我使用tensorflow 1.15，Keras 2.2和Python 3.7。

> setwd("C:/Users/Mezeix/Desktop/R/")
> model <- load_model_hdf5("my_model_W18_2c2.h5")
Error in load_model_hdf5("my_model_W18_2c2.h5") : 
  The h5py Python package is required to save and load models

如果我检查我得到了：

> reticulate::py_config()

NOTE: Python version was forced by use_python function

在计算机上安装tensorflow和Keras时遇到了很大的困难。我收到此消息，但我听不懂：

   > tf$constant("Hellow Tensorflow")
