问题 I'm stuck with an issue. I have a Python script that I would like to run on my OSX but seems that I crossed on many issues. To run the script I should have both Python and Moviepy installed. To install Moviepy I used this command: sudo pip install moviepy The response was: sudo: pip: command not found So I tried to install pip, with the command: sudo easy_install pip And got this answer: Searching for pip Best match: pip 9.0.1 Processing pip-9.0.1-py2.7.egg pip 9.0.1 is already the active

问题 In Spring Data R2DBC I can log SQL queries by using logging.level.org.springframework.data.r2dbc=DEBUG in the application.properties . However, this doesn't log the actual values that are bound as query parameters. How can I log the actual values of query parameters in Spring Data R2DBC? 回答1: This worked for me : logging: level: io.r2dbc.postgresql.QUERY: DEBUG # for queries io.r2dbc.postgresql.PARAM: DEBUG # for parameters I found it here 回答2: If you happen to use MySQL, you can get a low

问题 I have a knitr_kable output that I want to save as an HTML document from R. I need this to run automatically from my R script with no human involvement. For example: dt <- mtcars[1:5, 1:6] kable(dt, "html") %>% kable_styling(bootstrap_options = c("striped", "hover")) This has html output but the class is knitr_kable so I can't write it to a table or html file because it cannot be coerced to a dataframe. class(kable(dt, "html")) [1] "knitr_kable" Does anyone have a method for saving one of

问题 Hi how to set a label in spinner: ie the lable should initially visible when user clicke the spinner button options visible , when user select the option the label should replace with the new item,is it possible with spinner? 回答1: Spinners do not have "labels".

问题 I have a txt file that has multiple lines. Each line as text that is separated by space. Number of columns in each line may be different. I need to read each line one at a time, put it into data frame and print it. I tried this: x<-readLines("output.txt") for (i in 2:length(x) ) { data<-data.frame(x[[i]]) print(data) } I have to start from line number 2 becasuse line number 1 has some heading info that I dont need. For example, this prints out something like this: x[[2]] [1] " dcserver AIX

问题 I was trying .exceptionally and .handle but those don't seem to work. In scala, you can call a method on the future with a closure that is just like a finally block(it runs on exception AND on success) AND it propogates the exception or success up the chain as-is. I tried this... CompletableFuture<Object> future = newFuture.handle((r, e) -> { if(r != null) return r; else if(e != null) return e; else return new RuntimeException("Asdf"); }); Assert.assertTrue(future.isCompletedExceptionally());

问题 I am using the qrcode_gen() function from the qrcode package in R to generate a QR code, then place it on the top of a document (example linked below). The document is printed, written on, scanned, and stored as an image (.png) file. I would like to be able to read the QR code in R to get the imbedded text back. Eventually the whole process will be semi-automated in an Rshiny app, so I am hoping to keep everything in R , and not need to use an outside web tool to read the code. Has anyone

问题 I have an ASP.NET Core 2.1 app that I've hosted in an Azure app service. When executed locally I'm able to access the controller. But when I host in an Azure app I receive a 404. Here are the minimal steps to reproduce. In Visual Studio 2017 add a new project. Select ASP.NET Core Web Application. Select ASP.NET Core 2.1, API project template, no authentication, configure for HTTPS. Run the new app as a self hosted (not using IIS). Browse to https://localhost:5001/api/values. I get the
