Я загружаю свою модель, используя следующий код.
def load_model(checkpoint_path):
'''
Function that loads a checkpoint and rebuilds the model
'''
checkpoint = torch.load(checkpoint_path, map_location = 'cpu')
if checkpoint['architecture'] == 'resnet18':
model = models.resnet18(pretrained=True)
# Freezing the parameters
for param in model.parameters():
param.requires_grad = False
else:
print('Wrong Architecture!')
return None
model.class_to_idx = checkpoint['class_to_idx']
classifier = nn.Sequential(OrderedDict([
('fc1', nn.Linear(512, 1024)),
('relu1', nn.ReLU()),
('dropout', nn.Dropout(0.2)),
('fc2', nn.Linear(1024, 102))
]))
model.fc = classifier
model.load_state_dict(checkpoint['state_dict'])
return model
А во время бега
# Load your model to this variable
model = load_model('checkpoint.pt')
Я получаю следующую ошибку,
RuntimeError Traceback (самый последний вызов
прошлой)
