Leap Frame schema for PySpark Pipeline with only ML model (POST error)
johnnyasd12 opened this issue · comments
I've serialized my ML pipeline model from PySpark.
The pipeline I built contains only GBTClassifier without any other transformer for some purpose.
Thus the input format of the pipeline should be a N-dimensional vector.
I deployed the pipeline through docker provided by MLeap.
Then I try to do the prediction with Leap Frame created by myself.
According to #510 , I wrote the json format of Leap Frame like this:
{
"schema": {
"fields": [
{
"name": "features",
"type": {
"type": "tensor",
"base": "double",
"dimensions": [13]
}
}
]
},
"rows": [
[
[1.0, 2.0, 3.0, 4.0, 5.0, 6.0, 7.0, 8.0, 9.0, 10.0,
11.0, 2.0, 3.0]
]
]
}But I got error DeserializationException: invalid tensor when I try to POST the data to the docker server through curl.
The whole error message is as follow:

Is there something wrong with the input format?
Thanks.
Answer myself
The format in #510 seems to be outdated. It should be modified as follows:
{
"schema": {
"fields": [
{
"name": "features",
"type": {
"type": "tensor",
"base": "double"
}
}
]
},
"rows": [
[
{
"values":[1.0, 2.0, 3.0, 4.0, 5.0, 6.0, 7.0, 8.0, 9.0, 10.0,
11.0, 2.0, 3.0],
"dimensions": [13]
}
]
]
}then the POST request would be success.
