the trend step artifact used to keep track the time of the data so we know the expected trend of the input data. For example, on the first data which is trend_step = 1 the trend value is 10, then if the trend_step = 10 (the tenth data) our regressor will predict the trend value of the selected trend_step. this method is still in research to make it more efficient so it doesn't need to upload artifact every request
X is the sequence generated from df. df contains 2 columns (date and value). Size of X for this example is (1,60,1) with type np.array, X is sequence with size 1(number of data), 60(timestep), 1(value from 'value' column of df).
I want to build a real time data streaming anomaly detection service with clearml-serving
Oh, so the way it currently works clearml-serving will push the data in real-time into Prometheus (you can control the stats/input/out), then you can build the anomaly detection in grafana (for example alerts on histograms over time is out-of-the-box, and clearml creates the histograms overtime).
Would you also need access to the stats data in Prometheus ? or are you saying you need to process it before it gets there?
the last dimension is the value, like if the time series is univariate data the last dimension is 1 and if multivariate data the last dimension is depend on the number of datas feed to the model
It said the command --aux-config got invalid input

Make sense! I would suggest you add a GitHub issue with feature request for fast key/value storage that supports multi instance, I think this usage pattern will be greatly appreciated
BTW as an optimization I would use Task scalars (they are send in the background, you can relativity easily get the latest value etc.) do you also need it to be atomic ?
X is the sequence generated from df. df contains 2 columns (date and value). Size of X for this example is (1,60,1) with type np.array, X is sequence with size 1(number of data), 60(timestep), 1(value from 'value' column of df).
So in theory 1,60,-1 should work as a size for Triton, Are you getting an error?
(BTW: if you were to manually run the model inference I'm assuming you would have created a 3d matrix where the dims are 1,60,<batch_size>, is that correct?)
self.task.upload_artifact('trend_step', self.trend_step + 1)Out of curiosity why would every request generate an artifact ? Wouldn't it be better to report as part of the statistics ?
What would be the size / type of the matrix X (i.e. np.size / np.dtype) ?
Is there any references (vlog/blog) on deploying real-time model and do the continuous training pipeline in clear-ml?
Something along the lines of this one ?

Hmm EmbarrassedPeacock82
Let's try with--input-size -1 60 1 --aux-config input.format=FORMAT_NCHWBTW: this seems like a triton LSTM configuration issue, we might want to move the discussion to the Triton server issue, wdyt?
EmbarrassedPeacock82 are you using keras/pytorch etc for serving (i.e. Triton) ?
There is already a kafka server in clearml-serving, I think I'm lost on what you are looking to build here?
I want to build a real time data streaming anomaly detection service with clearml-serving
If there is new issue will let you know in the new thread
Thanks! I would really like to understand what is the correct configuration
I have tried to change dimension to [-1,60,1] but I got this error:

Hmm, how does your preprocessing code looks like?
I think this usage pattern will be greatly appreciated
BTW as an optimization I would use Task scalars (they are send in the background, you can relativity easily get the latest value etc.) do you also need it to be atomic ?
Yes it's atomic, Okay I will research more about the Task scalars
So in theory 1,60,-1 should work as a size for Triton, Are you getting an error?
(BTW: if you were to manually run the model inference I'm assuming you would have created a 3d matrix where the dims are 1,60,<batch_size>, is that correct?
Unfortunately it's not working, in (1,60,1) dimension I think there is no batch size information there. The input data shape is like this:
[[1,...,60]]. I need the first dimension to be dynamic so I can send more time series data at once: [[1,..,60], [61,..,120], [121,..,180]] <- like that
Oh, so the way it currently works clearml-serving will push the data in real-time into Prometheus (you can control the stats/input/out), then you can build the anomaly detection in grafana (for example alerts on histograms over time is out-of-the-box, and clearml creates the histograms overtime).
Would you also need access to the stats data in Prometheus ? or are you saying you need to process it before it gets there?
Is there any references to setup this? I'm not familiar about advanced features in clearml-serving
BTW: this seems like a triton LSTM configuration issue, we might want to move the discussion to the Triton server issue, wdyt?
Definitely!
Also, i'd like to ask about the alternative way of this issue. Is there any reference about integrating kafka data streaming directly to clearml-serving? because right now this issue raise as I'm using a nodejs service to mediate data from kafka to my clearml-serving
Okay, I will research about the features first. Thank you AgitatedDove14 for the support. If there is new issue will let you know in the new thread

Definitely!
Could you start an issue https://github.com/triton-inference-server/server/issues , and I'll jump join the conversation?
. Is there any reference about integrating kafka data streaming directly to clearml-serving?
There is already a kafka server in clearml-serving, I think I'm lost on what you are looking to build here?
I'm using a nodejs service to mediate data from kafka to my clearml-serving
Is this for the serving of requests? (following my question above)
I have timeseries dataset with dimension 1,60,1 which the first dimension is number of data, the second one is timestep
I think it should be --input-size 1 60 ` if the last dimension is the batch size?
(BTW: this goes directly to Triton configuration, it is the information Triton needs in order to run the model itself)
ZanyPelican5 Yes, I am using keras for serving (triton)
