@Oceania2018 hello. I clone the repository and add additional check if Value in the callCantext is null create new ThreadLocal (on screen changes)

this is my test program. predictions from the picture "Image"
@uzfm Are you saying the img_final is empty when second prediction? Yes.
I tried many options but nothing helped.
"var tensorr = tf.constant (imgR)" also doesn't work

@vshakhlin The syntax change seems act the same behaviour.

@uzfm @vshakhlin Just upgrade to v0.3.1 https://www.nuget.org/packages/SciSharp.Models.ImageClassification/0.3.1, it will resolve the prediction issue.

Thank you very much!!! works great.
Is it possible to see the result of the prediction for all classes?

@uzfm You can input multiple images at one time.
@vshakhlin You're correct, do you mind PR your fix?

@vshakhlin The fix is working great.

Hi, I have a problem with using np.where or condition operator using numpy.net. Seems like numpy net doesn't implement operator but looking resources online, its looks like it have been implemented. Is there any troubleshooting guide?
it says Operator '!=' cannot be applied to operands of type 'NDarray' and 'int'

Really love the project and what you all are trying to do but it looks like there are still some gaps in support / implementation. Any guesses when we will see a 1.0 release? Would love to be able to use tensorflow.net in production environments!
Haiping
@Oceania2018
@digital-synapse Next release will be v0.70.x aligned with tensorflow v2.7.0 & keras v2.7.0.
After that we're planning to release v1.0, it's usable in production in terms of architectual. Acutally it's already stable although there are many APIs/ NumPy not implemented, those missing stuff will be added gradually.
@digital-synapse Thanks for your fixing PR.

Thanks hailing. Glad to help. Any tips for getting 100% core utilization when using the CPU backend?

Hi does any know if it is possible to recognize keywords from audio streams using tensorflow.net?
Haiping
@Oceania2018
Probably yes, reference to https://www.tensorflow.org/tutorials/audio/simple_audio

Yes, i saw that. I am looking for the equivalent in tensorflow.NET
am new to this

or some guide that maps the terms from python to .net
Haiping
@Oceania2018
@franckm:matrix.org Just use the almost same syntax to translate.
Or you can use https://www.bountysource.com/ to ask someone else to help.

Has anyone been able to figure out a workaround for loading HDF5 (.h5) Keras models and using them for prediction? It's crucial to my project that these models can be imported directly without having to rebuild them every time, but there still doesn't seem to be a keras.models.load_model() implementation that returns a usable model yet.
Haiping
@Oceania2018
@thislookshard You just need to build once and load_weights. build model is not time cosuming.

hey.. any body experience memory leak in numpy.net?

Hello.If I want to make a prediction two different models I receive error. Everything is going for the first time good. In second time I get error on the first model.

@Oceania2018
@uzfm Are you using the latest version?
uzfm
@uzfm
ver. 0.3.1
Haiping
@Oceania2018
I'm saying the tf .net version.

@uzfm
Tf 1.15.1

@Oceania2018
As I know the latest version fixed the issue.

Try to upgrade ImageClassfication to v0.4.0
uzfm
@uzfm
Update 0.4.0 did not help
"task[ID]" is a new model.
I want to make simultaneous predictions on two different models.

Hi, I have a question on NumSharp. I'm trying to get started and learn the API a bit. The DocFX documents search feature doesn't seem to work though.
so as far as a guide of sorts, this is all I've found: https://3rdman.de/2020/08/numsharp-cheat-sheet/
is there anything else out there in terms of examples, guides, tutorials?

(sorry mean to say that the search doesn't go as deep as I'd like)

hi again, just following on my own question here. it looks like much of the docs Numpy.NET, also applies to NumSharp. For example, the suggestion to reshape a 1D array, and then just trial and error with numpy methods.

for example
input

using NumSharp;
var m = np.array(new double[]{1,2,3,4,5}).reshape(5,1);
m.ToString().Display();

var n = np.array(new double[,]{{1},{2},{3},{4},{5}});
n.ToString().Display();

output

[[1], 
[2], 
[3], 
[4], 
[5]]

[[1], 
[2], 
[3], 
[4], 
[5]]
rdthree
@rdthree
another one...
//this only works with a [,] array, a [] array doesn't have axes to swap
//benefit here is not having to type the size of elements in the reshape
var o = np.array(new double[,]{{1,2,3,4,5}}).swapaxes(0,1);
o.ToString().Display();
[[1], 
[2], 
[3], 
[4], 
[5]]
