Issues

1

1	AttributeError: module 'PIL.Image' has no attribute 'LINEAR'. Did you mean: 'BILINEAR'?

LINEAR-> BILINEAR: commit

2

在尝试训练的过程中报错：

3

  File "/home/cyl/Reconst/fcsgg/fcsgg/data/detection_utils.py", line 432, in generate_score_map
    masked_fmap = torch.max(masked_fmap, gaussian_mask * k)
RuntimeError: The size of tensor a (55) must match the size of tensor b (56) at non-singleton dimension 1

modify detection_utils.py: commit

Training

首先更改训练的配置文件./config/quick_schedules/Quick-FCSGG-HRNet-W32.yaml, (原文件使用预训练的参数)

MODEL:
  META_ARCHITECTURE: "CenterNet"
  HRNET:
    WEIGHTS: "output/FasterR-CNN-HR32-3x.pth"

更改为train from scratch

MODEL:
  META_ARCHITECTURE: "CenterNet"
  HRNET:
    WEIGHTS: ""  # Empty string to train from scratch

再运行：

1	python tools/train_net.py --num-gpus 1 --config-file configs/quick_schedules/Quick-FCSGG-HRNet-W32.yaml

成功训练✌

Git Submodule

What is a Git submodule?

A Git submodule allows a user to include a Git repository as a subdirectory of another Git repository. This can be useful when a project needs to include and use another project. For example, it may be a third-party library or a library developed independently for use in multiple parent projects. With submodules, these libraries can be managed as independent projects while being used in the user’s project. This allows for better organization and management of the code.

How to add a submodule to a project

To add an existing Git repository as a submodule to a project, the git submodule add command can be used. The command format is git submodule add <url> <path>, where <url> is the URL of the submodule repository and <path> is the storage path of the submodule in the project. For example, if a user wants to add the remote repository https://github.com/username/repo.git as a submodule to their project and store it in the my-submodule directory, they can use the following command:

1	git submodule add https://github.com/username/repo.git my-submodule

This will successfully add a submodule named my-submodule to the user’s project.
