"WLN00066-思科无线AP1240AG的快速配置手册提供了针对这款胖AP的初始设置指南,包括登陆信息、默认设置、射频和IP地址配置以及安全注意事项。" 这篇快速配置手册是为思科Aironet 1240AG系列无线接入点设计的,它主要关注的是如何快速有效地配置这个胖AP(FAT AP)。"胖AP"是指不依赖于无线控制器独立工作的接入点,它可以自行管理无线网络的连接和配置。 手册中指出,802.11a频率并不适用于1242G型号的AP,用户应关注802.11b和802.11g的相关内容。默认的登陆信息为用户名"Cisco"(区分大小写),密码同样为"Cisco"。AP的IP地址通常是通过DHCP动态获取,但如果无法获取,用户需要通过控制台接口手动配置IP地址、子网掩码和网关。 射频和IP地址的配置是初始化过程中的关键步骤。新购买的AP射频模块默认关闭,需要在配置时开启。在开始配置之前,确保有一台连接到同一网络的PC,并准备以下信息:AP的设备名称、802.11g和802.11a的SSID、SNMP管理信息(如果需要)、AP的MAC地址(如果使用Cisco IP地址设置软件),以及如果不能使用DHCP,需要手工地设定AP的IP信息。 关于安全,设备已经过FCC认证,RF射频对人体无害。不过,安装和运行时仍需注意:避免在设备运行时让天线靠近人体,特别是头部;设备应根据IEEE 802.3af标准和IEC 60950标准进行安装,同时设备内置电源保护措施,但电源输入不应超过其额定值。 安全警告部分强调了在连接电源前阅读安装手册的重要性,以及设备仅适用于符合特定电气标准的环境。此外,手册还包含了多语言的安全警告,以确保用户在安装和使用过程中遵循正确的操作流程,保障人身安全。 这份快速配置手册为用户提供了全面的指导,帮助他们成功地设置和启动思科1240AG无线AP,确保其在网络中的有效运作。

pytorch部分代码如下:train_loss, train_acc = train(model_ft, DEVICE, train_loader, optimizer, epoch,model_ema) for batch_idx, (data, target) in enumerate(train_loader): data, target = data.to(device, non_blocking=True), Variable(target).to(device,non_blocking=True) samples, targets = mixup_fn(data, target) output = model(samples) optimizer.zero_grad() if use_amp: with torch.cuda.amp.autocast(): loss = torch.nan_to_num(criterion_train(output, targets)) scaler.scale(loss).backward() torch.nn.utils.clip_grad_norm_(model.parameters(), CLIP_GRAD) if not (self._backward_hooks or self._forward_hooks or self._forward_pre_hooks or _global_backward_hooks or global_forward_hooks or global_forward_pre_hooks): return forward_call(*input, **kwargs) class LDAMLoss(nn.Module): def init(self, cls_num_list, max_m=0.5, weight=None, s=30): super(LDAMLoss, self).init() m_list = 1.0 / np.sqrt(np.sqrt(cls_num_list)) m_list = m_list * (max_m / np.max(m_list)) m_list = torch.cuda.FloatTensor(m_list) self.m_list = m_list assert s > 0 self.s = s self.weight = weight def forward(self, x, target): index = torch.zeros_like(x, dtype=torch.uint8) target = torch.clamp(target, 0, index.size(1) - 1) index.scatter_(1, target.unsqueeze(1).type(torch.int64), 1) index = index[:, :x.size(1)] index_float = index.type(torch.cuda.FloatTensor) batch_m = torch.matmul(self.m_list[None, :], index_float.transpose(0,1)) batch_m = batch_m.view((-1, 1)) x_m = x - batch_m output = torch.where(index, x_m, x) return F.cross_entropy(self.s*output, target, weight=self.weight) 报错: File "/home/adminis/hpy/ConvNextV2_Demo/train+ca.py", line 46, in train loss = torch.nan_to_num(criterion_train(output, targets)) # 计算loss File "/home/adminis/anaconda3/envs/wln/lib/python3.9/site-packages/torch/nn/modules/module.py", line 1051, in _call_impl return forward_call(*input, **kwargs) File "/home/adminis/hpy/ConvNextV2_Demo/models/utils.py", line 622, in forward index.scatter_(1, target.unsqueeze(1).type(torch.int64), 1) # target.data.view(-1, 1).
