the folowing is forward function of a standard model where RGB are separated
def forward(self, x1, x2, x3):
x1 = self.features_stage1A(x1)
x2 = self.features_stage1A(x2)
x3 = self.features_stage1B(x3)
# concatenate in dim1 (feature dimension)
x = torch.cat((x1, x2, x3), 1)
x = self.features_stage2(x)
x = self.avgpool(x)
x = torch.flatten(x, 1)
x = self.classifier(x)
return x
When I compress the model with a config file
nncf_config_dict = {
"model": "alexnet",
"pretrained": 1,
"input_info": [ {"sample_size": [1, 1, image_size, image_size] },
{"sample_size": [1, 1, image_size, image_size] },
{"sample_size": [1, 1, image_size, image_size] }
],
"log_dir": str(outdir),
"compression": {
"algorithm": "quantization",
"initializer": {
...
I got an error ... Are there any mofification to remove the error... It seems 2nd argument is not properly taken.

Hi timosy,
By referring to NNCF Configuration File Description, you are specifying each model input in the correct way. However, I observe that you are using AlexNet (Classification model) in the configuration file which should only has one model input. Therefore, all the config file examples from classification, object detection and semantic segmentation models only has one model input.
On the other hand, NLP models have more than 1 model inputs. Here are config file examples for multiple model inputs. Please try to add "type": "long" when specifying each model input. Hope this helps.
Regards,
Peh

Hi timosy,
This thread will no longer be monitored since we have provided suggestions. If you need any additional information from Intel, please submit a new question.
