根因分析

优化器槽变量形状不匹配，通常由于从具有不同架构或不兼容优化器状态的模型加载检查点导致。

English

Optimizer slot variable shape mismatch, often due to loading a checkpoint from a model with different architecture or incompatible optimizer state.

解决方案

  1. Load only the model weights, not optimizer state, by excluding optimizer variables when restoring:
model.load_weights('checkpoint.ckpt', by_name=True, skip_mismatch=True)
# Or use: model.load_weights('checkpoint.ckpt', skip_mismatch=True)
  2. Reinitialize the optimizer and train from scratch, or use a checkpoint that matches the current model architecture exactly.

无效尝试

常见但无效的做法:

  1. 80% 失败

    Checkpoint files are binary; manual modification corrupts them.

  2. 95% 失败

    This flag only controls device placement, not tensor shapes.
