How can I upload my pipeline model to edgeimpulse project?

Question/Issue:
Hello, I’m trying to upload simple model to edge impulse directly. But It can not be uploaded by direct model upload menu from my project. How could I upload my model?
The code below is what I am trying.

Project ID:
(onnx_upload_test - Pretrained model - Edge Impulse

Context/Use case:

import numpy as np
from sklearn.pipeline import Pipeline
from sklearn.preprocessing import StandardScaler
from sklearn.svm import SVC
from skl2onnx import convert_sklearn
from skl2onnx.common.data_types import FloatTensorType

Sample data for training

X_train = np.array([[1, 2, 3, 4, 5], [2, 3, 4, 5, 6], [3, 4, 5, 1, 2], [4, 5, 6, 7, 8], [5, 6, 7, 8, 9]])
y_train = np.array([0, 1, 2, 0, 1])

Create the pipeline

pipeline = Pipeline([
(‘scaler’, StandardScaler()), # StandardScaler
(‘svc’, SVC()) # SVC with probability
])

Fit the model

pipeline.fit(X_train, y_train)

evaluation

pipeline.fit(X_train, y_train)
X_test = np.array([[1, 2, 3, 4, 5], [3, 4, 5, 1, 2], [5, 6, 7, 8, 9], [4, 5, 6, 7, 8]])
y_test = np.array([0, 2, 1, 0])
print((X_test))
print((pipeline.named_steps[‘scaler’].transform(X_test)))
print(pipeline.predict(X_test))
score = pipeline.score(X_test, y_test)
print(“pipeline score:”, score)

Convert the pipeline to ONNX

Set the input shape to a fixed size (e.g., [1, 5] for batch size of 1)

initial_type = [(‘float_input’, FloatTensorType([1, 5]))]
final_types = [(‘output_label’, FloatTensorType([1, 1])), (‘output_probability’, FloatTensorType([1, 1]))]

onnx_model = convert_sklearn(pipeline, initial_types=initial_type, final_types= final_types)

Save the ONNX model

with open(‘svc_pipeline.onnx’, ‘wb’) as f:
f.write(onnx_model.SerializeToString())

Steps Taken:

  1. making pipeline model
  2. making onnx file from the code
  3. upload onnx file to the project

Expected Outcome:
simply upload
