            • Issue-1: max_df and min_df should be both int or both float.
            • Issue-2: At the prediction time you have to use the same CountVectorizer.
            • Issue-3: At the prediction time you have to use the transform method, not the fit_transform method of CountVectorizer.

            How to change the function parameters (visualize_topics_over_time) in BERTopic?

            I am using BERTopic to perform the topic modelling, everything works perfectly fine. However, since I am forcing the algorithm to give me 10 topics using nr_topics=10 as output, and when I visualize the topics overtime using topic_model.visualize_topics_over_time(topics_over_time, top_n_topics=10, width=1250, height=450), some colors are repeated for topics as there are only 7 colors mentioned in the function visualize_topics_over_time. I tried executing the same function in my python notebook with additional color values, but it gives me the following error:

            Two shiny widgets cannot be used at the same time to subset a dataframe
            Asked 2022-Jan-10 at 11:13

            I have the shiny app below in which I create a wordcloud. This wordcloud is based on the shiny widgets in the sidebar. The selectInput() subsets it by label, the Maximum Number of Words: is supposed to show the maximum count of words that will be displayed in the wordcloud and the Minimun Frequency the minimum frequency that a word needs to be displayed. Those widgets are reactive and are based on the df() function which creates the dataframe needed for the wordcloud. The proble is that when I subset using input$freq the dataframe has fewer rows than needed to subset with input$max as well so nothing is displayed.

            I'm not totally sure, but since you say

            when the app is launched nothing is displayed

            It could be related to this bug.

            I created this solution.

            This looks complicated, but it really isn't. Simply define the following function (wordcloud2a()), then use it where you'd normally use wordcloud2().

            blue/green deployment to portainer using gitlab CI/CD
            Asked 2021-Dec-02 at 07:39

            I have webservice using websockets, and need to implement zero-downtime deployment. Because I don't want drop existing connections on deploy, I've decided to implement blue/green deploy. My actual solution looks like:

            1. I've created two identical services in portainer, listening on different ports. Every service has set in node environments some identifier, for example alfa and beta
            2. Both services are hidden behind load balancer, and balancer is periodically checking status of each service. If service responds on specific route (/balancer-keepalive-check) with string "OK", this service is active and balancer can routing to this service. If service is responding with string "STOP", balancer mark this service as inaccessible, but active connections will be preserved
            3. which service is active and which is stopped is synced over redis. In redis there are keys lb.service.alfa and lb.service.beta which can contains values 1 for active and 0 for inactive. Example of implementation /balancer-keepalive-check route in nestjs:

            Work with large raster mosaics in R without merging them to a single file (like lidR catalog)
            Asked 2021-Nov-30 at 16:52

            The lidR package has a neat way to work with huge (pointcloud) datasets: The catalog function (doc here) avoids loading the dataset to memory and can treat mosaics [datasets that are spread across multiple (non-overlapping) tiles] as single dataset. It loads required tiles on-the-fly during computations in an intelligent way. It is great to avoid working with huge files (multiple GBs) and keep memory requirements lean if only working with small parts of the dataset.

            Is there a similar convenient/memory-efficient/"lidR-catalog-way" to process large raster mosaics in R? Or more put in a more general way: Is there a way to work with mosaic raster datasets in R without merging them first?

            I am aware of the mosaic (doc) and merge functions, which allow me to merge my tiled raster mosaic into a single raster dataset. I also found that gdal will do so a lot faster and memory efficient. Here is a R-snippet for this:

            You should look into the terra package which provides exactly the functionality you're looking for through virtual raster tiles (VRTs). We can use them to treat a collection of raster files on disk as a single raster file while taking advantage of the API to do a majority of the same tasks as you can do through the raster package.

            First, let's create a sample of 4 rasters using the example straight from the ?terra::vrt() documentation.

            Well, Theraot has made an answer so please see his answer instead, but if you want to see how I explain it, here you go.

            First, Theraot asked me

            Is this something specific of the font? What is DialogBox (is it a WindowDialog? I don't see you call popup)? Given that you don't know how to describe the problem, can you provide a video?

            I responded

            @Theroat It's a Node that contains the dialog box text and a rectangle on which the text stands just for it looking good. and by dialog_box I don't mean a popup just a undertale-like dialog box.

            and I sent a video like he asked : https://drive.google.com/file/d/18QrOOw_FZ3MgboVrv59b4sDrFG-AxlmR/view?usp=sharing

            He responded

            About the video, I was hoping to see it running. However, I notice something on the video you provided. The Label is before the Panel in the scene tree. So the Panel could cover the text. To avoid that, move the Label below the Panel in the scene tree. I don't have the same font file you are using, but I replicated the setup in the video with a different font, and besides the position of the Label, it works fine for me.

            And well that's the whole thing, See the comments for what happened in more info.

            As your MKL library is installed in /usr/include/mkl location, you can set MKLROOT environment variable as export MKLROOT=/usr/include/mkl Another alternate is, to install oneAPI Base & HPC Toolkits from where you can get Intel MKL library package and initialize oneAPI environment which automatically sets the MKLROOT. For more details regarding oneAPI Base Toolkit and oneAPI HPC Toolkit refer https://software.intel.com/content/www/us/en/develop/articles/installation-guide-for-intel-oneapi-toolkits.html
