转换onnx模型失败

[huanyingjun]

hi 我在转换 https://huggingface.co/BAAI/bge-small-en-v1.5/tree/main/onnx 这个模型，遇到下面的错：

2024-07-05 16:21:59.085678: I tensorflow/core/platform/cpu_feature_guard.cc:182] This TensorFlow binary is optimized to use available CPU instructions in performance-critical operations.
To enable the following instructions: AVX2 FMA, in other operations, rebuild TensorFlow with the appropriate compiler flags.

TypeError: Exception encountered when calling layer "tf.gather" (type TFOpLambda).

Value passed to parameter 'indices' has DataType float32 not in list of allowed values: int16, int32, int64

Call arguments received by layer "tf.gather" (type TFOpLambda):
  • params=tf.Tensor(shape=(30522, 384), dtype=float32)
  • indices=tf.Tensor(shape=(1, 512), dtype=float32)
  • validate_indices=None
  • axis=0
  • batch_dims=0
  • name=None

请帮忙看一下，谢谢
