QUESTION
I'm following a Google Colab guide from Roboflow to train the MobileNetSSD Object detection model from Tensorflow on a custom dataset. Here is the link to the colab guide: https://colab.research.google.com/drive/1wTMIrJhYsQdq_u7ROOkf0Lu_fsX5Mu8a
The data set is the example set from the Roboflow website called "Chess sample" which everyone who registers an account on the website gets in their workspace folder. Here is the link to get that setup: https://blog.roboflow.com/getting-started-with-roboflow/
When following the Colab all steps are running completely fine until the step "Train the model". The following message is printed:
...ANSWER
Answered 2022-Apr-07 at 16:25Yes, indeed - downgrading numpy will solve the issue - we saw this same bug in the Roboflow Faster RCNN tutorial. These new installs are now present in the MobileNet SSD Roboflow tutorial notebook.

I have a Stryker test with this stryker-config.json:
ANSWER
Answered 2021-Aug-20 at 09:19No, unfortunately there's no way currently.
You'll basically need to run mutation testing subsequently against both projects. Remember you can keep most of the config file, just pass the specific project to the Stryker command line using -p/--project-file option, so it will look like dotnet stryker --config-file-path PATH --project-file PROJECT.
Alternatively, if you have a solution, you can look into ideas in this discussion. Basically it's either unstable or you'll require some manual scripting.

QUESTION
Say I have parent class A: Codable with subclasses B1: A and B2: A. A different class Main: Codable in my application has a pointer to an A which can either be a B1 or a B2 but cannot be an A (I'm effectively treating A as an abstract class).
When I am decoding a Main, I run into an issue where it is incorrectly being decoded to an abstract A rather than a B1 or B2, even though the value store in A will always be a B1 or a B2. I have tried implementing custom init(from decoder: Decoder) and func encode(to encoder: Encoder)s in the subclasses but when I step through Main's decode logic in my running app, I never see those subclasses' implementations being called.
Is this because Main has an A and has no idea to even attempt to decode it as a B1 or a B2? Do I need to call those subclasses decoders specifically? If the latter is that case, those subclasses decoders couldn't call the parent decoder because that would create an infinite loop.
Here is what my code currently looks like:
...ANSWER
Answered 2022-Mar-19 at 18:31You need to have a custom init(from:) in Main and decode a to the right subclass directly
QUESTION
As far as I know, a modern JPEG decoder produces the same image when given the same input JPEG file.
Normally, we create JPEG files in such a way that the decoded image is an approximation of some input image.
Is the JPEG format flexible enough to allow lossless encoding of arbitrary input images with a custom encoder?
I'd image you'd at least have to fiddle with how quantization tables are used to essentially disable them? Perhaps something else?
(To be clear, I don't mean the special 'lossless' mode in JPEG that many decoders don't support. I am talking about using the default, mainstream code path through the decoder.)
...ANSWER
Answered 2022-Mar-10 at 23:07No. Even with no quantization, the RGB to YCbCr transformation is lossy in the low few bits. Also the chroma channels are then downsampled, but that step can be skipped. While the DCT is mathematically lossless, in reality it is lossy in the least significant bit or two in the integer representation.
QUESTION
I have encountered the following problem My task is as follows, I need to play streaming video (raw h264 video over UDP protocol) on a 3d object. At the moment I'm using FFmpegInteropX to set a MediaSource to a Windows object.Media.Playback.MediaPlayer. Media Player works in frame server mode, then I subscribe to the videoFrameAvailable event and transmit the resulting frame to Unity
The problem is that the performance on Hololens2 (UWP) is quite low, I can't get enough smoothness and low latency if I use texture sizes greater than 720x720. At the same time, if I run the application on a PC, I can play everything up to 4096x4096 smoothly and without delay. Perhaps someone has some ideas on how to improve performance on Hololens2?
...ANSWER
Answered 2022-Mar-02 at 13:12The problem was copying from CPU to GPU, the SharpDX library allowed copying frames directly to Idirect3dsurface. I'm attaching the code, maybe it will be useful. Direct3D11 helpers is available in the microsoft documentation https://docs.microsoft.com/en-us/windows/uwp/audio-video-camera/screen-capture-video#helper-wrapper-classes

QUESTION
i am trying to get a hardware decoder from media foundation. i know for sure my gpu supports nvdec hardware decoding. i found an example on github which gets the encoder, nvenc without any problem. but when i switch the params to decoder, i either get a bad hresult or a crash. i tried even getting a software decoder by changing the hardware flag, and still bad hresult. any one have an idea what is wrong? i cant think of anything else left for me to try or change
...ANSWER
Answered 2022-Jan-10 at 15:30There might be no dedicated decoder MFT for hardware decoding (even though some vendors supply those). Hardware video decoding, in contrast to encoding, is available via DXVA 2 API, and - in turn - is covered by Microsoft H264 Video Decoder MFT.
This stock MFT is capable to decode using hardware and is also compatible with D3D9 and D3D11 enabled pipelines.

From MSDN:
CODECAPI_AVDecVideoAcceleration_H264Enables or disables hardware acceleration....
Maximum Resolution 4096 × 2304 pixels The maximum guaranteed resolution for DXVA acceleration is 1920 × 1088 pixels; at higher resolutions, decoding is done with DXVA, if it is supported by the underlying hardware, otherwise, decoding is done with software.
...
DXVA The decoder supports DXVA version 2, but not DXVA version 1. DXVA decoding is supported only for Main-compatible Baseline, Main, and High profile bitstreams. (Main-compatible Baseline bitstreams are defined as profile_idc=66 and constrained_set1_flag=1.)
To decode with hardware acceleration just use Microsoft H264 Video Decoder MFT.
QUESTION
I'm trying to implement the ability to use Azure B2C with Spring Boot's Webflux Security. While there's no official library to actually do this, it was said by someone at Microsoft that Spring Security 5's native features could support Azure B2C. I've followed this repository (though it's not webflux based) to get an idea on pulling this off. The JWT tokens are validated via the audience UUID for an application.
Once I try to actually supply a JWT token to a request, I'm getting a HTTP 401 error stating Authentication failed: Failed to validate the token.
The thing is that in the example repository, they're using the endpoint https://login.microsoftonline.com/{tenantId}/v2.0 for the issuer url.
On the other hand, the JWT token returned from B2C has the issuer https://{tenantName}.b2clogin.com/{tenantId}/v2.0/.
If I use the issuer https://{tenantName}.b2clogin.com/{tenantId}/v2.0/ instead, the JWT decoder won't be able to find the configurations.
So now I feel there's an inconsistency on what the issuer URL actually is, which prevents Webflux from actually being able to perform the authentication.
Here's the code I have for the security.
...ANSWER
Answered 2021-Dec-18 at 19:50The issuer URL https://login.microsoftonline.com/{tenantId}/v2.0 is for Azure AD.
Because Azure B2C is dependent on profiles that are defined, you have to use https://{tenantName}.b2clogin.com/tfp/{tenantId}/{profileName}/v2.0/ as the issuer URL.
While https://{tenantName}.b2clogin.com/{tenantId}/{profileName}/v2.0/ is also a valid issuer, Spring Security will complain of an inconsistent issuer URL due to the issuer actually being https://{tenantName}.b2clogin.com/{tenantId}/v2.0/.
It appears that Azure B2C doesn't have a general issuer nor a JWK list that contains all of the keys.
