代码就是demo中的例子，例子中SparseFeat的vocabulary_size大小设置为最大值+1
fixlen_feature_columns = [SparseFeat(feat, data[feat].max() + 1,embedding_dim=4)
for feat in sparse_features]
当我将其改为1时代码仍能成功运行
fixlen_feature_columns = [SparseFeat(feat, 1,embedding_dim=4)
for feat in sparse_features]
而当我禁用gpu，使用cpu训练模型时tensorflow则会提示我越界错误
