正如文档中所述，我正在尝试在 Common Voice 数据集上训练 DeepSpeech 模型。但它给出了以下错误：

我的本地机器规格如下：

蟒蛇3.7；库达 10.1；CuDNN 7.6.5；张量流-GPU 1.15.2；GPU GTX 1050 钛

我还安装了以下包和库来准备环境：

!apt-add-repository universe
!apt-get install sox libsox-fmt-mp3 cmake libblkid-dev e2fslibs-dev libboost-all-dev libaudit-dev libeigen3-dev zlib1g-dev libbz2-dev liblzma-dev
!python3.7 -m pip install sox
!python3.7 -m pip install deepspeech-gpu
!python3.7 -m pip install tensorflow-gpu==1.15.2
!python3.7 -m pip install numpy==1.19.5
!python3.7 -m pip install progressbar2
!python3.7 -m pip install progressbar

!python3.7 -m pip install deepspeech
!git clone --branch v0.9.3 https://github.com/mozilla/DeepSpeech
!python3.7 -m pip install --upgrade --force-reinstall -e ./DeepSpeech/
!git clone https://github.com/kpu/kenlm.git
!mkdir -p build
!cmake kenlm
!make -j 4
!wget https://github.com/mozilla/DeepSpeech/releases/download/v0.9.3/deepspeech-0.9.3-checkpoint.tar.gz
!curl -LO "https://github.com/mozilla/DeepSpeech/releases/download/v0.9.3/native_client.amd64.cuda.linux.tar.xz"
!mkdir native_client
!tar xvf native_client.amd64.cuda.linux.tar.xz -C native_client

我在本地机器和 google colab vm 上都遇到了同样的问题。

编辑：我还将我的 cuda 和 cudnn 版本分别更改为 10.0 和 7.5.6。但是错误已经存在。

感谢您提供额外的信息 Soroush。

LD_LIBRARY_PATH看起来不错，我将假设这些库实际上位于这些路径中。

接下来，我要确保代码在 GPU 本身上执行。

代码可能无法在 GPU 上执行的原因有很多。您提到您的环境是根据 DeepSpeech PlayBook 设置的，这意味着它使用的是 Docker。那是对的吗？如果是这样，您是使用该gpus -all参数生成的 Docker 容器吗？

接下来要检查的是是否nvtop从 DeepSpeech 报告 GPU 活动。当DeepSpeech.py脚本运行时，这应该会导致高compute负载，在nvtop. 如果你没有看到这个，这意味着代码可能没有在 GPU 上执行，这可以解释No OpKernel错误。

我已经解决了这个问题。该问题是由 Tensorflow 的版本引起的。正如我之前提到的，我使用了 Tf 1.15.2，而我必须使用 Tf 1.15.4。

我在 DeepSpeech Discourse 上看到过类似的错误，问题是 CUDA 安装。

你的$LD_LIBRARY_PATH环境变量的值是多少？

您可以通过以下方式找到它：

$ echo $LD_LIBRARY_PATH
/usr/lib/x86_64-linux-gnu:/usr/local/cuda/bin:/usr/local/cuda/lib64:/usr/local/cuda-11.2/targets/x86_64-linux/lib

我的怀疑是 CUDA 无法找到正确的库。
