今天,我发现我无法打开anaconda导航器,该导航器之前运行得还不错。同时,spyder也无法打开,但是可以使用jupyter笔记本和anaconda提示符。我按照在线说明尝试了不同的方法。
1) conda update anaconda-navigator and reboot the system
2) anaconda-navigator --reset

,但显示错误如下:

During handling of the above exception, another exception occurred:

我需要从“ http://www.elections.state.md.us ”下载一些 csv 文件。
这是我的代码。
url <- "http://www.elections.state.md.us/elections/2012/election_data/index.html"
# recognize the links
links <- getHTMLLinks(url)
filenames <- links[str_detect(links,"_General.csv")]
filenames_list <- as.list(filenames)
filenames
# create a function
downloadcsv <- function(filename,baseurl,folder){
dir.create(folder,showWarnings = FALSE)
fileurl <- str_c(baseurl,filename)
if(!file.exists(str_c(folder,"/",filename))){
download.file(fileurl,
destfile = str_c(folder,"/",filename))
# 1 sec delay between files
Sys.sleep(1)
}
}
library(plyr)
l_ply(filenames_list,downloadcsv,
baseurl = "www.elections.state.md.us/elections/2012/election_data/",
folder = "elec12_maryland")

错误结果如下:
download.file(fileurl, destfile = str_c(folder, "/", filename)) 中的错误:URL 'www.elections.state.md.us/elections/2012/election_data/State_Congressional_Districts_2012_General.csv' 中不支持方案
然而,当我尝试将网址粘贴到 IE 中时,它确实起作用了。那么我的代码有什么问题呢?
任何想法都会有帮助,谢谢。
我遇到的部分代码如下,其中workers是类对象的列表:
worker_threads = []
for worker in workers:
worker_fn = lambda worker=worker: worker.run(sess, coord, FLAGS.t_max)
t = threading.Thread(target=worker_fn)
t.start()
worker_threads.append(t)

通常我期望lambdais的语法lambda x : func(x),但在这里worker=worker用于什么?
