根因分析
模型包含 TFLite 后训练量化不支持的操作或数据类型，例如不支持的激活函数或动态范围。
English
The model contains operations or data types that are not supported by TFLite's post-training quantization, such as unsupported activations or dynamic ranges.

-
Use selective quantization: converter.optimizations = [tf.lite.Optimize.DEFAULT]; converter.target_spec.supported_types = [tf.float16]; then convert.
-
Disable quantization for problematic layers: converter.optimizations = [] and convert without optimization.
-
Replace unsupported ops with TFLite-compatible alternatives, e.g., replace tf.nn.relu6 with tf.nn.relu.
无效尝试
常见但无效的做法:
-
90% 失败
The converter cannot handle the incompatible ops, leading to crashes.
-
80% 失败
The model structure may not support post-conversion quantization.
