pipeline

Using sparks vector assembler the columns to be assembled need to be defined up front. However, if using the vector-assembler in a pipeline where the previous steps will modify the columns of the data frame how can I specify the columns without hard coding all the value manually? As df.columns will not contain the right values when the constructor is called of vector-assembler currently I do not see another way to handle that or to split the pipeline - which is bad as well because CrossValidator will no longer properly work. val vectorAssembler = new VectorAssembler() .setInputCols(df.columns

This question already has answers here : Why does shell ignore quotes in arguments passed to it through variables? [duplicate] (3 answers) Closed 3 years ago . If i use this command in pipeline, it's working very well; pipeline ... | grep -P '^[^\s]*\s3\s' But if I want to set grep into variable like: var="grep -P '^[^\s]*\s3\s'" And if I put variable in pipeline; pipeline ... | $var nothing happens, like there isn't any matches. Any help what am I doing wrong? The robust way to store a simple command in a variable in Bash is to use an array : # Store the command names and arguments

With the release of Gitlab 11.7 in January 2019, we get the new key feature Publish releases for your projects . I want precisely what the screenshot on that page shows and I want to be able to download compiled binaries using the releases API . I can do it manually. Of course, instructions for the manual approach can be found here on stack overflow . The problem I need help with is doing it as part of a CI/CD pipeline, which is not covered by the answers one can find easily. The release notes contain a link to the documentation , which states: we recommend doing this as one of the last steps

I am working on datapaths and have been trying to understand branch instructions. So this is what I understand. In MIPS, every instruction is 32 bits. This is 4 bytes. So the next instruction would be four bytes away. In terms of example, I say PC address is 128. My first issue is understanding what this 128 means. My current belief is that it is an index in the memory, so 128 refers to 128 bytes across in the memory. Therefore, in the datapath it always says to add 4 to the PC. Add 4 bits to the 128 bits makes 132, but this is actually 132 bytes across now (next instruction). This is the way

I'd like to integrate git into production pipeline to stage 3dsmax files. While it is alright to work with git through TortoiseGit, I'd like to communicate with it from the Maxscript to add custom menu commands to 3dsmax. Should I parse git status output text to determine folder status or should I use some wrapping tool to correctly communicate with git? I was thinking about gitsharp since it is easy to call dotNet objects from Maxscript, but I didn't use external dotNet programs. My own attempt to solve this resulted in parsing git status. Seems cleaner and easier to implement. On the other
