kandi X-RAY | tracer Summary

tracer is a Perl library typically used in Performance Management, Monitoring, Framework applications. tracer has no bugs, it has no vulnerabilities, it has a Strong Copyleft License and it has low support. You can download it from GitHub.

traceR consists of two modified R interpreters, one for runtime measurements called [timeR][] and [r-instrumented][] for analyzing runtime and memory behavior. The results are gathered in an SQLite database for convenient analysis. [timeR]: [r-instrumented]: The current version of traceR was inspired by the original traceR from the [Reactor group] at Purdue University. This version has improved usability and analysis capability compared to the original. We added profiling for vector data structures, dynamic memory and CPU utilization profiles and profiling for parallel R programs.

            MoleculerJs with Jaeger tracing: how to trace follow up action calls (new spans) in one trace
            Asked 2021-Jun-14 at 21:33

            I would like to display all my traces like in the examples from the moleculer-jaeger package:

            But what i get is something like this: All spans you can see in this picture should be within the main trace (gateway).

            Here is my moleculer.config:

            1. This version already has a built-in jager tracer, see the documentation.
            2. In order for the events to be nested, it is necessary to transfer the context inside the actions, use calls instead of, so they will be nested.

            How to make the object bounce back with turtle
            Asked 2021-Jun-13 at 02:33

            I want to make the yellow block jump on the line when there are other shapes. Also, how could I make the screen to close when the yellow block touches the other blocks.

            I have though about using the time module and put time.sleep for 1 seconds after blockself.goto(0,30) then make the block go down to (0,0). However, when I did that the whole screen frozed for 1 second. This means that the time.sleep was not aimed for the blockself(yellow block) it self. Is there any way to fix this.



            Answered 2021-Jun-13 at 02:33

            We can make the yellow block vertical jump independent of the other motion using the same mechanism I gave you for the horizontal block motion, ontimer(). The jump() method below is invoked by the keyboard event, moving the yellow block up and down as a series of timer events:



            Best way to compute the moving average of word vectors in JAX
            Asked 2021-Jun-10 at 08:13

            Let say I have a matrix W of shape (n_words, model_dim) where n_words is the number of words in a sentence and model_dim is the dimension of the space where the word vectors are represented. What is the fastest way to compute the moving average of these vectors ?

            For example, with a window size of 2 (window length = 5), I could have something like this (which raises an error TypeError: JAX 'Tracer' objects do not support item assignment):



            Answered 2021-Jun-09 at 16:50

            This looks like you're trying to do a convolution, so jnp.convolve or similar would likely be a more performant approach.

            That said, your example is a bit strange because n is never larger than 4, so you never access any but the first four elements of W. Also, you overwrite the previous value in each iteration of the inner loop, so each row of new_W just contained a scaled copy of one of the first four rows of W.

            Changing your code to what I think you meant and using index_update to make it compatible with JAX's immutable arrays gives this:



            Copy a VkImage after TraceRaysKHR to CPU
            Asked 2021-Jun-06 at 09:08

            Copying a VkImage that is being used to render to an offscreen framebuffer gives a black image.

            When using a rasterizer the rendered image is non-empty but as soon as I switch to ray tracing the output image is empty:



            Answered 2021-Jun-06 at 09:08

            Resolved by now: When submitting the command buffer to the queue it would require an additional vkQueueWaitIdle(m_queue) since ray tracing finishes with a certain latency



            open telemetry InMemorySpanExporter not reseting after test case is completed
            Asked 2021-Jun-03 at 20:02

            Open Telemetry InMemorySpanExporter not resetting after test class is complete. This is causing span_list = self.memory_exporter.get_finished_spans() to be empty for the 2nd test class.



            Answered 2021-Jun-03 at 19:32

            Your description was not clear but I can share why you are running into AssertionError. This is happening because we don't allow setting global tracer provider once it is already set; link to code which does that. There can only be one global tracer provider. So, when the call to trace.set_tracer_provider made in second test it logs warning without doing anything hence your second attempt to set pipeline was unsuccessful i.e second exporter never received the spans.



            Python : Using Turtle-graphics, having issue with Screen.tracer() and Screen.update(). Placement of’ update() ‘ makes my code run / not-run properly
            Asked 2021-Jun-03 at 15:41

            I am trying to make a Pong game and as you can see in the screenshot ( at the end of this question ), In the right hand side I have created a paddle.

            Everything works fine in following code, when I press Up and Down arrows, the paddle moves up and down.

            Kindly note placement of statement “ screen.update()”

            Why is my code not working in SECOND CASE

            Because you haven't put a screen.update() everywhere you make a change that you want the user to see. Specifically the go_up() and go_down() methods:



            Turtle Screen.tracer(0) doesn't stop all animation
            Asked 2021-Jun-02 at 22:13

            I thought using Screen.tracer(0) disabled animation in Python Turtle Graphics. However in the following program, if you comment out screen.update(), there is still some animation happening - the turtle trail gets drawn although the turtle doesn't "move" (or get updated). What is happening here please? Is there way to make updating the screen completely manual?



            Answered 2021-Jun-02 at 18:26

            No, screen.tracer(0) doesn't stop all animation. Some turtle commands like end_fill() invoke screen.update() directly, some like dot() invoke it due to other methods that they in turn invoke. You only advise the system when you call update(), not control it completely.

            Put your update() calls where you believe you need them, and don't assume certain methods force an update, otherwise future updates of turtle might break your code. (I.e. someone might actually fix turtle.)

            is it possible to jit a function which uses jax.numpy.unique?
            Asked 2021-May-30 at 03:49

            The following code does not work:



            Answered 2021-May-30 at 03:49

            No, for the reasons you mention, there's currently no way to use jnp.unique on a non-static value.

            In similar cases, JAX sometimes adds extra parameters that can be used to specify a static size for the output (for example, the size parameter in jax.numpy.nonzero) but nothing like that is currently implemented for jnp.unique. If that is something you'd like, it would be worth filing a feature request.



            Using Feign builder requests doesn't send trace-id, span-id to child clients but using rest template is showing all headers on child clients
            Asked 2021-May-28 at 06:05

            I'm making a sequential request using Feign Builder. There are no x-b3-traceid,x-b3-spanid .. in the title of the request. That's why the log my last client appears on the zipkin.

            I use spring boot 2.4.2 , spring cloud 2020.0.0 , feign-core 10.10.1 , feign-okhttp 10.10.1. I have tried spring-cloud-openfeign and i achieved wanted result. But i don't want to use this lib. There are requests when using Feign Builder and Rest Template in here. I dont' see same log at zipkin.

            Answered 2021-Mar-01 at 08:16

            The problem might be related to the fact that you're creating the Feign builder manually via Feign.builder() factory method. We're unable to instrument that call. You should create a bean (via SleuthFeignBuilder.builder) and inject that into your code.

            Install tracer

            Currently, traceR has only been tested on a Linux system. It can likely be compiled on other Unix-like systems, but chances of it working in Windows are relatively slim. It is strongly recommended to use the [traceR installer][] to install traceR as it will automatically install both timeR and r-instrumented in a directory of your choice with minimum hassle. If you want to install traceR manually anyway (NOT recommended), just use make install PREFIX=/where/you/want/it to install traceR in a directory of your choice. It will assume that timeR and r-instrumented are installed in the directories "timed" and "instrumented" in the destination directory, although you can override this in the configuration file. If there is no tracer.conf file in the target directory, the installation process will copy a sample file.
