@kerryJo
thanks
KerryJo
@kerryJo
@delzac tell me about the image segmentation loss function?
delzac
@delzac
What would you like to know about it? Typically you can just use fmeasure https://github.com/Microsoft/CNTK/blob/master/bindings/python/cntk/losses/__init__.py#L424
KerryJo
@kerryJo
@delzac
Can You see my code together?
I want to make the CNTK version of the Keras model, and finally I want to use cntk well.
I would appreciate your help.
delzac
@delzac
There's no keras model in your link. The cntk unet model in the link you provided. And use the fmeasure loss function instead of the dice_coefficient in your git repo
KerryJo
@kerryJo
I'm making the keras model cntk.
to cntk..
delzac
@delzac
In your git repo, its already in written in cntk.

@kerryJo
Finished Epoch[1 of 20]: [Training] loss = -0.988350 20, metric = -98.84% 20 20.703s ( 1.0 samples/s);
Oh! thanks bro!!
It only works once and the train stops.
Is it normal?
delzac
@delzac
It shouldn't, did any error appear?
KerryJo
@kerryJo
yes
no error just stop
delzac
@delzac
You need to do some debugging now i guess.
KerryJo
@kerryJo
Okay. Thank you.
Can I debug and ask again?
delzac
@delzac
sure :)
KerryJo
@kerryJo
@delzac Is there a Unet example in cntkx?
KerryJo
@kerryJo
Found!
KerryJo
@kerryJo
hi. how to used copy the Weight value of the PretrainedModel?
Typically, once you have a reference to the parameter object (W) you can access the attribute (W.values) and you can get the weights in numpy
KerryJo
@kerryJo
@delzac Thanks bro. Fina
I finally found a good example of CNTK image segmentation.
I do not know why I do not include this in the tutorial.
Many people do not know if good examples exist.
Did not I know it alone?

Hi, I understand that 2.7 is the last release.. What does that mean. As far as i understand it works in C# for both training deep neural networks and recalling from them. However the documentation and examples in C# seem incomplete. Furthermore since it is the last release no further major release will be made . Is that a correct summary of the current and final state of affairs?
delzac
@delzac
@Gregor959 Python APIs and related work are complete. C# is more patchy, but still better than anything out there (compared to other frameworks)
Gregor
@Gregor959
@delzac .. there are many deeplearning libraries ( Tensorflow, keras) using python and also more popular ones and ones that are still getting supported with future development. As far as C# and F# are concerned this was the only officially supported library on .net . The .net community has been waiting 5 years for microsoft to get the deep learning on .net . We have existing projects on .net that are screaming for deeplearning... Will the c# interface and examples be completed under 2.7 ? How is the F# looking: 100% complete as pythons's , including the documentation?
delzac
@delzac
@Gregor959 For more C# examples, you can check out https://github.com/anastasios-stamoulis/deep-learning-with-csharp-and-cntk

@Gregor959 I'm also wondering about the "last main release" notice for version 2.7. Does anybody know if MS has abandoned CNTK? I've spent months developing a project using CNTK and now I feel like I should start over with a different AI toolkit. So far, I've had no luck trying to find out from MS. At this point, I think it would be a waste of time to put any time on learning any thing new for CNTK.
willprgm
@willprgm
Does anyone know anything about the fate of CNTK? Has MS abandoned it?
delzac
@delzac
@willprgm you can check out Microsoft/CNTK#3646 on the way forward

@maxima120
I have joined to ask the same question.. @willprgm
"The CNTK 2.7 release has full support for ONNX 1.4.1, and we encourage those seeking to operationalize their CNTK models to take advantage of ONNX and the ONNX Runtime." - I fail to understand relation between CNTK future and ONNX. I thought ONNX is just model export/import format..

@maxima120
Amazon should take over. Anyone knows Bezos phone number?
duxianghong
@duxianghong
in the future, MS will publish the CNTK 3....?
so the CNTK 2.7 is the last main release. right?
delzac
@delzac
Yes cntk2.7 will be the last main release. More details pleases check out here #3646

Hi! I'm training my own data with complex objects:

python 3.5
CNTK 2.6
no GPUs
epoch=20
C.CNTK.TRAIN_E2E = True C.CNTK.E2E_MAX_EPOCHS = 20
C.NUM_ROI_PROPOSALS = 2000 C.DATA.NUM_TRAIN_IMAGES = 39
C.DATA.NUM_TEST_IMAGES = 7 C.DATA.PROPOSAL_LAYER_SCALES = [4, 8, 12]
...
So, I'm getting such outputs, is it normal or does it mea a error?

@delzac
@TchuBotin Sounds like you need to update your GPU driver

@TchuBotin

Thx @delzac, but I don't have GPU only CPU:

Selected CPU as the process wide default device.
Using base model: AlexNet

Perhaps, my problem is that the first time I'm trying CNTK.

Hi guys, I created a python package a couple of days back which helps generate ML code based a yml like file called "mlm". This package as of now supports keras and a little of tf2. I would really appreciate if you guys could help out with the CNTK part as well.
Thank you
