问题描述
我正在使用R 3.4.2.我正在按照decryptr 包
I am using R 3.4.2. I am following example from decryptr package
library(decryptr)
# Download captchas
captcha <- download_tjmg(dest = 'img')
keras_tjmg <- decryptrModels::read_model('tjmg')
最后一行代码会产生错误
Last line of code produce an error
Error in keras::load_model_hdf5(file_path) :
The h5py Python package is required to save and load models
我试图从终端重新安装h5py软件包.我还安装了keras软件包.我可以在pyrthon中导入h5py程序包，但是Rstudio无法以某种方式识别它.
I have tried to reinstall h5py package from terminal. I have also installed keras package. I can import h5py package in pyrthon, but Rstudio doesn't recognize it somehow.
推荐答案
我以前从未安装过这些软件包，但是我按以下步骤进行操作并成功！也花了一些时间，因为除了您报告的内容外，它还给我带来了许多错误.
I've never installed these packages before, but I proceeded as follows and succeeded! It took a bit of time, too, because it gave me a variety of errors besides what you reported.
最后，我想出了这个:在终端中，
Finally, I came up with this: in terminal,
pip uninstall h5py
pip install h5py
pip uninstall keras
pip install keras
我在Python中检查import h5py是否运行正确(第一次，它给我DLL失败.)然后在R中，重启后，
I checked in Python that import h5py runs true (the first time, it gave me a DLL failure.) Then in R, after restarting,
install.packages("reticulate")
install.packages("tensorflow")
install.packages("keras")
install.packages("h5py")
devtools::install_github("decryptr/decryptr")
devtools::install_github("decryptr/decryptrModels")
library(keras)
install_keras()
# Check where Python's looked for
reticulate::py_config()
library(decryptr)
library(decryptrModels)
captcha <- captcha_download_tjmg(dest = 'img')
keras_tjmg <- read_model('tjmg')
我的sessionInfo()如下:

让我知道是否可以解决.
Let me know if this works out.
