根因分析

cuDNN RNN层初始化失败，原因是给定cuDNN版本不支持的隐藏大小、批大小或序列长度。

English

cuDNN RNN layer initialization fails due to unsupported hidden size, batch size, or sequence length for the given cuDNN version.

解决方案

  1. Reduce the hidden size or batch size to a value supported by cuDNN (e.g., hidden size divisible by 32 or 64):
model.add(tf.keras.layers.LSTM(units=256, return_sequences=True))
# Try units=128 or 64 if 256 fails
  2. Set the environment variable TF_CUDNN_USE_AUTOTUNE=0 to disable cuDNN autotuning, which may bypass the BAD_PARAM error:
export TF_CUDNN_USE_AUTOTUNE=0
python train.py

无效尝试

常见但无效的做法:

  1. 90% 失败

    The error is about invalid parameters, not memory.

  2. 75% 失败

    Older cuDNN versions may not support required RNN operations.
