Error: all query identities do not appear in gallery

I am following the instruction for market1501 dataset, but I am getting this error.

all query identities do not appear in gallery

import torchreid

datamanager = torchreid.data.ImageDataManager(
    root="/content/drive/MyDrive/AI_projects/AIC23_Track1_UWIPL_ETRI/deep-person-reid/reid-data",
    sources="market1501",
    targets="market1501",
    height=256,
    width=128,
    batch_size_train=32,
    batch_size_test=100,    
    transforms=["random_flip", "random_crop"]
)

model = torchreid.models.build_model(
    name="osnet_x1_0",
    num_classes=datamanager.num_train_pids,
    loss="softmax",
    pretrained=True
)

model = model.cuda()

optimizer = torchreid.optim.build_optimizer(
    model,
    optim="adam",
    lr=0.0003
)

scheduler = torchreid.optim.build_lr_scheduler(
    optimizer,
    lr_scheduler="single_step",
    stepsize=20
)

engine = torchreid.engine.ImageSoftmaxEngine(
    datamanager,
    model,
    optimizer=optimizer,
    scheduler=scheduler,
    label_smooth=True
)

engine.run(
    save_dir="log/osnet_x1_0_market",
    max_epoch=200,
    eval_freq=60,
    print_freq=10,
    test_only=True
)

What can I do to resolve this issue?
