[QGIS-Developer] Error trying to import linear_model from sklearn in Qgis

[Akbar Gumbira]

Even though it works fine on my local (QGIS 3.8.3, Mac, Python 3.7, sklearn
0.21.3), I often encountered that error, most of the time related to floats
operation (e.g np.float32 not JSON serializable)

Python Console

Use iface to access QGIS API interface or Type help(iface) for more info

>> from sklearn import linear_model

>> import numpy as np

>> X = np.random.randint(10, size=(10, 2))

>> Y = np.random.rand(10, 1)

>> X.shape, Y.shape

((10, 2), (10, 1))

>> reg = linear_model.LinearRegression().fit(X, Y)
