python tools/train.py --config_file configs/softmax_triplet.yml MODEL.DEVICE_ID "('0')" DATASETS.NAMES "('market1501')" DATASETS.ROOT_DIR "(r'./data')

环境说明：

matplotlib>=3.2.2
numpy>=1.18.5
opencv-python>=4.1.2
Pillow>=7.1.2
PyYAML>=5.3.1
requests>=2.23.0
scipy>=1.4.1

ps:arrow_right:**该训练reid项目与person_search项目是独立的！！**训练完reid后，把训练好的权重放到person_search/weights下，切换到peron_search项目中在去进行reid识别【不然有时候会报can't import xxx】。

参数说明：

--config_file: 配置文件路径，默认configs/softmax_triplet.yml

--weights: pretrained weight path

--neck: If train with BNNeck, options: bnneck or no

--test_neck: BNNeck to be used for test, before or after BNNneck options: before or after

--model_name: Name of backbone.

--pretrain_choice: Imagenet

--IF_WITH_CENTER: us center loss, True or False.

配置文件的修改：

(注意：项目中有两个配置文件，一个是config下的defaults.py配置文件，一个是configs下的yml配置文件，一般配置yml文件即可，当两个配置文件参数名相同的时候以yml文件为主，这个需要注意一下)

configs文件:

以softmax_triplet.yml为例：

SOLVER:
  OPTIMIZER_NAME: 'Adam' # 优化器
  MAX_EPOCHS: 120  # 总epochs
  BASE_LR: 0.00035
  IMS_PER_BATCH: 8  # batch
TEST:
  IMS_PER_BATCH: 4 # test batch
  RE_RANKING: 'no'
  WEIGHT: "path"  # test weight path
  FEAT_NORM: 'yes'
OUTPUT_DIR: "/logs" # model save path
