kandi X-RAY | pdl Summary

pdl is a Perl library typically used in Testing, Performance Testing applications. pdl has no bugs, it has no vulnerabilities and it has low support. However pdl has a Non-SPDX License. You can download it from GitHub.

PDL ("Perl Data Language") gives standard Perl the ability to compactly store and speedily manipulate the large N-dimensional data arrays which are the bread and butter of scientific computing. PDL turns Perl into a free, array-oriented, numerical language similar to (but, we believe, better than) such commercial packages as IDL and MatLab. One can write simple perl expressions to manipulate entire numerical arrays all at once. Simple interactive shells, pdl2 and perldl, are provided for use from the command line along with the PDL module for use in Perl scripts.

            Plot previous day levels misses the first candle of the day
            Asked 2021-May-29 at 15:37

            I am new to pine script coding. I am just trying to plot the previous day's high and the previous day's low in the current day's level. It seems to draw/plot correctly for the rest of the day candles, but the levels/lines are missed on the first candle of the current day. How can that be corrected?

            The levels seem to be drawn correctly after the first candle. Same is the case with stepline as well.

            ANSWER

            Answered 2020-Dec-16 at 06:36

            The exception message is very clear, Elasticsearch never assigns the replica of the same primary shard on the same node for high availability reasons.

            a copy of this shard is already allocated to this node [[research-pdl][0], node[5zzXP2kCQ9eDI0U6WY4j9Q], [P], s[STARTED], a[id=J7IX30jBSP2jXl5-IGp0BQ]]

            And as you have a single node cluster, so you will not have another other node where your replicas can be assigned.

            Solutions

            1. Add more nodes to your cluster, so that replicas can be assigned on other nodes. (preferred way)
            2. Reduce the replica shards to 0, this can cause data-loss and performance issues. (if at all, you don't have the option to add data-nodes and you want the green state for your cluster).

            You can update the replica counts using cluster update API.

            Subprocess opened with PIPE still reading input from terminal
            Asked 2020-Jun-08 at 18:52

            Python App

            My Python 3.6.8 app runs on CentOS 7.6, and:

            • Provides a GUI using Kivy 11.1.1.
            • Opens a sub-process from someone else.
            • The sub-process provides a custom shell.
            • When opened with pipes as below, the sub-process still reads from the terminal.
            • It ignores my app's commands to stdin.
            • But my app does receive output from the sub-process via the pipe.

            Sub-Process

            • The sub-process controls a device.
            • It normally provides an interactive shell.
            • I need to control it from my app.
            • To launch it, I invoke a compiled binary.
            • It uses some Perl modules.
            • Its workings are unknown to me.

            You are trying to use await inside a function that is not declared async. The function is the anonymous function/lambda that you're passing to forEach. The async on the outer function doesn't matter at all here. async/await doesn't work with nested lambda functions.

            Consider some ideas on how to work with async/await in forEach loops: Using async/await with a forEach loop
