UNet model : pretrained InceptionV4 encoder not available #675
Description
Hi, while playing around with different encoders i've noticed that the pretrained weights+ model for the inceptionv4 encoder is not available because of some SSL Certificate issue:
Code I used:
unet = smp.Unet(
encoder_name="inceptionv4",
encoder_weights="imagenet",
classes=6,
activation=None,
encoder_depth=5,
decoder_channels=[256, 128, 64, 32, 16],
in_channels=3,
)The error:
SSLCertVerificationError Traceback (most recent call last)
