RuntimeError: The size of tensor a (28) must match the size of tensor b (14) at non-singleton dimension 2

When use the pre-trained model VOLO-D4-448， the error as flow:
Traceback (most recent call last):

Hi, did you fix it? I meet same problem.

class VOLO(nn.Module):
def init(self, layers, img_size=640, in_chans=3, patch_size=8, stem_hidden_dim=64,
embed_dims=None, num_heads=None, downsamples=None, outlook_attention=None,
mlp_ratios=None, qkv_bias=False, qk_scale=None, drop_rate=0., attn_drop_rate=0.,
drop_path_rate=0., norm_layer=nn.LayerNorm, post_layers=None, return_mean=False,
return_dense=True, mix_token=True, pooling_scale=2, out_kernel=3,
out_stride=2, out_padding=1):

image_size大小需要修改成你自己定义的！
