Scratching my head on this one. I've simply added a new field to a model.

Answered 2022-Mar-26 at 05:02I suspect that adding a new field isn't the cause of the problem - it's just coincidence that the problem arose at the same time as you made this change. The clue is in the traceback:

I try to rebuild an electron app but I got this error regarding the epoll installation.

Answered 2021-Nov-09 at 06:01I have a same problem too, but i am using a serialport not epoll.
So, I think the cause of this problem is electron modules not the native module.
QUESTION
What would be the best way to set up a GCP monitoring alert policy for a Kubernetes CronJob failing? I haven't been able to find any good examples out there.
Right now, I have an OK solution based on monitoring logs in the Pod with ERROR
severity. I've found this to be quite flaky, however. Sometimes a job will fail for some ephemeral reason outside my control (e.g., an external server returning a temporary 500) and on the next retry, the job runs successfully.
What I really need is an alert that is only triggered when a CronJob is in a persistent failed state. That is, Kubernetes has tried rerunning the whole thing, multiple times, and it's still failing. Ideally, it could also handle situations where the Pod wasn't able to come up either (e.g., downloading the image failed).
Any ideas here?
Thanks.

QUESTION
I have implemented a Convolutional Neural Network in C and have been studying what parts of it have the longest latency.
Based on my research, the massive amounts of matricial multiplication required by CNNs makes running them on CPUs and even GPUs very inefficient. However, when I actually profiled my code (on an unoptimized build) I found out that something other than the multiplication itself was the bottleneck of the implementation.
After turning on optimization (-O3 -march=native -ffast-math
, gcc cross compiler), the Gprof result was the following:
Clearly, the convolution2D
function takes the largest amount of time to run, followed by the batch normalization and depthwise convolution functions.
The convolution function in question looks like this:
...ANSWER
Answered 2022-Mar-10 at 13:57Looking at the result of Cachegrind, it doesn't look like the memory is your bottleneck. The NN has to be stored in memory anyway, but if it's too large that your program's having a lot of L1 cache misses, then it's worth thinking to try to minimize L1 misses, but 1.7% of L1 (data) miss rate is not a problem.
So you're trying to make this run fast anyway. Looking at your code, what's happening at the most inner loop is very simple (load-> multiply -> add -> store), and it doesn't have any side effect other than the final store. This kind of code is easily parallelizable, for example, by multithreading or vectorizing. I think you'll know how to make this run in multiple threads seeing that you can write code with some complexity, and you asked in comments how to manually vectorize the code.
I will explain that part, but one thing to bear in mind is that once you choose to manually vectorize the code, it will often be tied to certain CPU architectures. Let's not consider non-AMD64 compatible CPUs like ARM. Still, you have the option of MMX, SSE, AVX, and AVX512 to choose as an extension for vectorized computation, and each extension has multiple versions. If you want maximum portability, SSE2 is a reasonable choice. SSE2 appeared with Pentium 4, and it supports 128-bit vectors. For this post I'll use AVX2, which supports 128-bit and 256-bit vectors. It runs fine on your CPU, and has reasonable portability these days, supported from Haswell (2013) and Excavator (2015).
The pattern you're using in the inner loop is called FMA (fused multiply and add). AVX2 has an instruction for this. Have a look at this function and the compiled output.
QUESTION
I am having a hard time getting to know how to create Ansible roles that are following the best practices according to documentation. The following use-case which I am looking at is e.g. enabling Filebeat on host. Filebeat can be configured by placing a module definition in /etc/filebeat/modules.d
folder.
It works fine when I am adding modules. Idempotence is working, everytime, on each run of the role (playbook), a given set of modules is enabled.
But what I should do when I decide that a given module is not longer needed? I remove it from role, rerun a playbook, so that all other modules are enabled. But: the previous run enabled a module that I am not installing directly with role after changes. So my server state is still altered in a way that is different than the role is imposing itself.
My question is: should I take care of removing modules before I apply them so I always start from, let's say, fresh state?

QUESTION
I wrote this script to search a lot of text files (~100,000) for 4 different search criteria and export to 4 separate files, I thought it would be more efficient to perform all 4 searches on each file as it is loaded vs doing 4 full searches like the first iteration below does. I may be missing some other major inefficiencies as I am pretty new to powershell.
I have this script re written from the first version to the second, but can't figure out how to get the path and data to display together like the first version did. I am struggling to reference the object within the loop, and have pieced this second version together, which is working, but not giving me the path to the file which is necessary.
It seems like I am just missing one or two little things to get me going in the right direction. Thanks in advance for your help

Answered 2021-Dec-23 at 14:54[edit - thanks to mklement0 for pointing out the errors about speed and the -SimpleMatch
switch. [grin]]
the Select-String
cmdlet will accept a -Path
parameter ... and it is FAR [i was thinking of Get-Content
, not Get-ChidItem
] faster than using Get-ChildItem
to feed the files to S-S
. [grin]
also, the -Pattern
parameter accepts a regex OR
pattern like Thing|OtherThing|YetAnotherThing
- and it accepts simple string patterns if you use the -SimpleMatch
switch parameter.
what the code does ...
- defines the source dir
- defines the file spec
- joins those two into a wildcard file path
- builds an array of string patterns to use
- calls
Select-String
with a path and an array of strings to search for - uses
Group-Object
and a calculated property to group the matches by the last part of.Line
property from theS-S
call - saves that to a $Var
- shows that on screen
at that point, you can use the .Name
property of each GroupInfo
to select the items to send out to each file AND to build your file names.
