小编Oli*_*ann的帖子

我正在做一些非常基本的JSON操作来学习一些Go,并且它有效,除了一件事似乎关闭,我必须编写分配.(map[string]interface{})和.([]interface{})访问JSON中的条目,特别是如果它们是孩子的孩子等等.

看到这里(也在Go Playground:https://play.golang.org/p/Wd-pzHqTsU):

package main

import (
    "fmt"
    "encoding/json"
)

func main() {
    JSON := []byte(`{"key1":"val1","key2":{"c1key1":"c1val1"},"key3":[{"c2key1":{"c3key1":"c3val1"}}]}`)
    fmt.Printf("%s\n", JSON)
    var d map[string]interface{}
    json.Unmarshal(JSON, &d)
    fmt.Println(d["key3"].([]interface{})[0].(map[string]interface{})["c2key1"].(map[string]interface{})["c3key1"])
    d["key3"].([]interface{})[0].(map[string]interface{})["c2key1"].(map[string]interface{})["c3key1"] = "change1"
    fmt.Println(d["key3"].([]interface{})[0].(map[string]interface{})["c2key1"].(map[string]interface{})["c3key1"])
    JSON, _ = json.Marshal(d)
    fmt.Printf("%s\n", JSON)
}

哪个回报:

{"key1":"val1","key2":{"c1key1":"c1val1"},"key3":[{"c2key1":{"c3key1":"c3val1"}}]}
c3val1
change1
{"key1":"val1","key2":{"c1key1":"c1val1"},"key3":[{"c2key1":{"c3key1":"change1"}}]}

现在在Python中我只是直接访问键/值而不是定义我每次访问的类型,而不是fmt.Println(d["key3"].([]interface{})[0].(map[string]interface{})["c2key1"].(map[string]interface{})["c3key1"])你做的print d["key3"][0]["c2key1"]["c3key1"]

Python示例:

import json

JSON = '{"key3": [{"c2key1": {"c3key1": "c3val1"}}], "key2": {"c1key1": "c1val1"}, "key1": "val1"}'
print JSON
d = json.loads(JSON)
print d["key3"][0]["c2key1"]["c3key1"]
d["key3"][0]["c2key1"]["c3key1"] = "change1"
print d["key3"][0]["c2key1"]["c3key1"]
JSON …

所以我在下面有我的构建脚本,一切都运行得很好,除非我保存的文件不是我的app.scss文件,而是导入到该文件中的sass任务,该任务不会运行.所以我的大口观察正在观看,但不是我猜的所有文件.不知道如何解决这个问题.我以为我指定使用"/*.scss"观看所有文件

我会喜欢这方面的帮助.

谢谢!

我正在尝试tm通过text2vecLDA 实现从-package运行 AssociatedPress 数据集。

我面临的问题是数据类型的不兼容：AssociatedPressis atm::DocumentTermMatrix又是slam::simple_triplet_matrix. text2vec然而期望输入x 到text2vec::lda$fit_transform(x = ...)要Matrix::dgTMatrix。

因此，我的问题是：有没有办法强制DocumentTermMatrix接受text2vec?

最小（失败）示例：

library('tm')
library('text2vec')

data("AssociatedPress", package="topicmodels")

dtm <- AssociatedPress[1:10, ]

lda_model = LDA$new(
  n_topics = 10,
  doc_topic_prior = 0.1,
  topic_word_prior = 0.01
)

doc_topic_distr =
  lda_model$fit_transform(
    x = dtm,
    n_iter = 1000,
    convergence_tol = 0.001,
    n_check_convergence = 25,
    progressbar = FALSE
  )

...这使：

base::rowSums(x, na.rm = na.rm, dims = dims, …
