Can you provide an example of what you mean?
In Example,
import numpy as np
from sklearn.datasets import make_classification
from torch import nn
import torch.nn.functional as F
from skorch import NeuralNetClassifier
from tune_sklearn import TuneGridSearchCV
X, y = make_classification(1000, 20, n_informative=10, random_state=0)
X = X.astype(np.float32)
y = y.astype(np.int64)
class MyModule(nn.Module):
def __init__(self, num_units=10, nonlin=F.relu):
super(MyModule, self).__init__()
self.dense0 = nn.Linear(20, num_units)
self.nonlin = nonlin
self.dropout = nn.Dropout(0.5)
self.dense1 = nn.Linear(num_units, 10)
self.output = nn.Linear(10, 2)
def forward(self, X, **kwargs):
X = self.nonlin(self.dense0(X))
X = self.dropout(X)
X = F.relu(self.dense1(X))
X = F.softmax(self.output(X))
return X
net = NeuralNetClassifier(
MyModule,
max_epochs=10,
lr=0.1,
# Shuffle training data on each epoch
iterator_train__shuffle=True,
)
params = {
"lr": [0.01, 0.02],
"module__num_units": [10, 20],
}
gs = TuneGridSearchCV(net, params, scoring="accuracy")
gs.fit(X, y)
print(gs.best_score_, gs.best_params_)
I do not want to save only the best case of gs
, but I want to save all the models from all the results of the experiment.
for example ,
I want to save the best performance value for each experiment in (lr, num_units) (0.01, 10) , (0.01, 20) , (0.02, 10) , (0.02, 20)
Hey @sungreong we actually removed this feature but am happy to reintroduce support. I'll push a PR soon!
Hi, I have a question.
When using TuneSearchCV, can you save all the models with the highest performance for each trial?
