Task-specific GCA - 全部问题已解决!
═══════════════════════════════════════════════════════════════════
✅ 已解决的5个问题:
1. ✅ torchpack: command not found
位置: START_PHASE4A_TASK_GCA.sh
解决: export PATH=/opt/conda/bin:$PATH
2. ✅ 预训练模型路径 (命令行)
位置: START_PHASE4A_TASK_GCA.sh
解决: 移除 --model.encoders.camera.backbone.init_cfg.checkpoint
3. ✅ 预训练模型配置 (配置文件)
位置: multitask_BEV2X_phase4a_stage1_task_gca.yaml
解决: init_cfg: null
4. ✅ init_weights自动加载
位置: bevfusion.py init_weights()
解决: 检查init_cfg为null时跳过
5. ✅ decoder.neck返回列表
位置: bevfusion.py forward_single()
解决: if isinstance(x, list): x = torch.cat(x, dim=1)
═══════════════════════════════════════════════════════════════════
现在启动:
docker exec -it bevfusion bash
cd /workspace/bevfusion
bash START_PHASE4A_TASK_GCA.sh
输入 'y' 确认
═══════════════════════════════════════════════════════════════════
启动后应该看到:
