我刚刚在RStudio中安装了Keras，我按照网页上的说明使用了mnist数据集，但是它给出了未加载数据集的错误消息。
我尝试了以下代码：
library(keras)
install_keras()
mnist <- dataset_mnist()
我也尝试了这段代码：
library(keras)
library(tensorflow)
install_keras()
mnist <- dataset_mnist()
但是我收到以下消息：
Error in py_get_attr_impl(x, name, silent) :
AttributeError: module 'tensorflow' has no attribute 'VERSION'
请，您能帮我解决这个问题吗？
答案 0 :(得分：2)
在PC上使用较早版本的tensorflow对我有用。在const SelectTagsDropdown = styled(Dropdown)`
margin: ${props => props.margin || '1em 0em 1em 0em'};
multiple: ${props => props.multiple};
`
