causal-conv1d和mamba-ssm上述方法安装失败，可以见链接，采用whl安装。

关于NameError: name 'selective_scan_cuda_core问题，是跟cd kernels/selective_scan && pip install .这个安装不成功有关，（分析原因应该是cuda版本不对）

NameError: name 'selective_scan_cuda_core' is not defined. Did you mean: 'selective_scan_flop_jit'?

测试代码，在classification/models/vmamba.py最后添加，并运行

device = torch.device("cuda:0")
hidden_dim = 3  # 假设 VSSBlock 的隐藏维度为 64
network = VSSM(hidden_dim).to('cuda:0')
# 随机生成一张输入图片作为示例
input_image = torch.randn(1, 3, 224, 224)  # 假设输入图片大小为 224x224，通道数为 3（RGB图像）
input_image = input_image.to(device)
# 前向传播
output = network(input_image)
# 输出结果的大小
print("Output shape:", output.shape)

输出结果，表示成功配置
