ov.single.cytotrace2 function error

[WeiQin2001]

Prediction of absolute developmental potential using CytoTrace2部分：
运行到这一步时：
results = ov.single.cytotrace2(adata,
use_model_dir="cymodels/5_models_weights",
species="mouse",
batch_size = 10000,
smooth_batch_size = 1000,
disable_parallelization = False,
max_cores = None,
max_pcs = 200,
seed = 14,
output_dir = 'cytotrace2_results'
)

出现以下报错：”

I have fixed this issue in the latest version.
