hi,
I’m traying to do a 3d ml, and when reaching the point of model.predict([xx,yy)], it gives me this error … and dont know what to do.
I’ve used as start point this dash
import numpy as np
import plotly.express as px
import plotly.graph_objects as go
from sklearn.svm import SVR
mesh_size = .02
margin = 0
df = px.data.iris()
X = df[['sepal_width', 'sepal_length']]
y = df['petal_width']
print("X es : ",X)
print("X tipo : ",type(X))
# Condition the model on sepal width and length, predict the petal width
model = SVR(C=1.)
model.fit(X, y)
# Create a mesh grid on which we will run our model
x_min, x_max = X.sepal_width.min() - margin, X.sepal_width.max() + margin
y_min, y_max = X.sepal_length.min() - margin, X.sepal_length.max() + margin
xrange = np.arange(x_min, x_max, mesh_size)
yrange = np.arange(y_min, y_max, mesh_size)
xx, yy = np.meshgrid(xrange, yrange)
# Run model
pred = model.predict(np.c_[xx.ravel(), yy.ravel()])
pred = pred.reshape(xx.shape)
# Generate the plot
fig = px.scatter_3d(df, x='sepal_width', y='sepal_length', z='petal_width')
fig.update_traces(marker=dict(size=5))
fig.add_traces(go.Surface(x=xrange, y=yrange, z=pred, name='pred_surface'))
fig.show()
