bug描述 Describe the Bug

我们尝试使用https://github.com/PaddlePaddle/PaddleSpeech/blob/aae9fa7f3cb9f4daefa422fd3613d15a46e43038/paddlespeech/t2s/exps/syn_utils.py#L473 进行声码器的模型转静态图,paddle.signal.istft 报错,但我们在训练和测试过程中从未遇到过这个问题,是否是paddle.signal.istft 在做静态图转换时产生错误

istft函数中,参数shape或size分别设置的多少呢?c , n_fft, hop_length, win_length

istft函数中,参数shape或size分别设置的多少呢?c , n_fft, hop_length, win_length

在istft函数中,n_fft= 48, hop_length=12,win_length=48, 当输入数据c的shape为[1, 25, 9026],输出数据c的shape为[1, 108300],该数据为在模型测试阶段在forward函数中的打印输出,能够正常执行。

进行声码器的模型转静态图时,打印的c.shape 为[1, 25, var shape_0.tmp_0_slice_0 : LOD_TENSOR.shape(1,).dtype(int32).stop_gradient(False)],n_fft= 48, hop_length=12,win_length=48 ,输出c的c.shape无法打印。

这里是我们采用的声码器动转静代码:

from paddlespeech.t2s.exps.syn_utils import voc_to_static
from paddlespeech.t2s.exps.syn_utils import get_voc_inference
def voc_static(args):
    # Init body.
    print(args)
    print(args.voc_config)
    with open(args.voc_config) as f:
        voc_config = CfgNode(yaml.safe_load(f))

    print("========Args========")
    print(yaml.safe_dump(vars(args)))
    print("========Config========")

    # vocoder
    voc_inference = get_voc_inference(
        voc=args.voc,
        voc_config=voc_config,
        voc_ckpt=args.voc_ckpt,
        voc_stat=args.voc_stat)
    print("voc done!")

    # whether dygraph to static
    print(args.inference_dir)
    if args.inference_dir:
        # vocoder
        voc_inference = voc_to_static(
            voc_inference=voc_inference,
            voc=args.voc,
            inference_dir=args.inference_dir)
def voc_to_static(voc_inference,
                  voc: str='pwgan_csmsc',
                  inference_dir=Optional[os.PathLike]):
    voc_inference = jit.to_static(
        voc_inference, input_spec=[
            InputSpec([-1, 80], dtype=paddle.float32),
        ])

    paddle.jit.save(voc_inference, os.path.join(inference_dir, voc))
    voc_inference = paddle.jit.load(os.path.join(inference_dir, voc))
    return voc_inference

在执行原版hifigan代码(没有采用istft函数)时,正常运行,在inference文件夹下生成hifigan_csmsc.pdiparams,hifigan_csmsc.pdiparams.info,hifigan_csmsc.pdmodel。

但当我们使用了带有istft函数对应的代码和训练后的模型进行静态图转换时,在执行voc_to_static时失败。

@longRookie "但当我们使用了带有istft函数对应的代码和训练后的模型进行静态图转换时" 我是否可以理解为你在复现 istftNet 然后动转静失败了?如果是 istft 模块动转静有问题,请提供最小可复现代码(仅有 istft 模块的组网代码),否则无法确定是 istft 的问题还是你的写法问题
