            Your dask and distributed versions have gone out of sync, 2021.4.0 versus 2021.4.1. Updating dask should fix this. Note that you need to ensure that the exact same versions are also in the environment you are using for YARN.

            Answered 2021-Mar-10 at 10:54

            I want to configure the state to perform a certain action if curl returns an error.

            There is a Salt state called http which can query a URL and return the status. Using this (instead of curl) we can check for the status code(s) (200, 201, etc.), as well as matching text. Then we can use requisites to run subsequent states depending on the success/failure of the http.query.

            Example:

            I have added a check for status code of 200, you can omit - status: 200 if you don't care about the status code.

            ANSWER

            Answered 2021-Feb-02 at 06:08

            The requisites that we mention, such as require, watch, etc. should be references to other states that are "scheduled" to run on the targets.

            About watch

            Even though the path is created by installing the "realvnc" package, there is no Salt state to handle the path. That is why it is showing the error.

            Quoting from documentation for watch:

            A watch requisite is used to add additional behavior when there are changes in other states.

            So if you want to watch on a file, then there should be a state that "handles" the file using the file module.

            About require

            Also, while specifying require you are referring to pkg module, so Saltstack would look for pkg.installed for realvnc. Whereas you are using chocolatey.installed.

            So with below modifications it should work fine.

            Answered 2020-Sep-22 at 05:37

            I've got some experience with rasterio, but I am not nearly a master with it. If I remember correctly, rasterio requires you to have installed the program GDAL(both binaries and python utilities), and some other dependencies listed on the PyPi page. I don't use conda at the moment, I like to use the regular python 3.8 installer with pip. Given what I'm seeing with your installation, I would uninstall rasterio and follow a different installation procedure.

            I follow the instructions listed here: https://rasterio.readthedocs.io/en/latest/installation.html
            This page also has separate instructions for those using Anaconda.

            The GDAL installation is by far the most annoying but once it's done, the hard part is over. The python utilities for both rasterio and gdal can be found here:
            https://www.lfd.uci.edu/~gohlke/pythonlibs/#gdal
            The second link is also provided on the PyPi page but I like to keep it bookmarked because there's a lot of good resources there!

            It looks like this question has an answer in the comments. I'm going to copy a response from Nick Becker

            Dask's distributed scheduler is single threaded (CPU and GPU), and Dask-CUDA uses a one worker per GPU model. This means that each task assigned to a given GPU will run serially, but that the task itself will use the GPU for parallelized computation. You may want to look at the Dask documentation and explore Dask.Array (which also supports GPU arrays).
