tensorflow环境安装配置

1. 下载匹配cuda的kaldi镜像

Ubuntu 20.04 including Python 3.8
NVIDIA CUDA 11.6.0
cuBLAS 11.8.1.74
NVIDIA cuDNN 8.3.2.44
NVIDIA NCCL 2.11.4 (optimized for NVLink?)
rdma-core 36.0
NVIDIA HPC-X 2.10
OpenMPI 4.1.2rc4+
OpenUCX 1.12.0
GDRCopy 2.3
Nsight Systems 2021.5.2.53
TensorRT 8.2.2
SHARP 2.5
DALI 1.9

• 下载命令：docker pull nvcr.io/nvidia/kaldi:22.01-py3
  找包的过程，可以参考之前docker的那篇文章。

docker run --gpus ‘“device=all”’ -itd -v /home/work/wang:/home/work/wang
-v /opt/wfs1/aivoice:/opt/wfs1/aivoice
–net host
–name wyr_tf_cuda11.6
–shm-size=8g
nvcr.io/nvidia/kaldi:22.01-py3 bash

2. 配置pip 和 conda

   vim ~/.pip/pip.conf
   添加如下内容

[global]
index-url = https://pypi.tuna.tsinghua.edu.cn/simple
[install]
trusted-host=mirrors.aliyun.com

3. 配置conda镜像

vim ~/.condarc

channels:
  - defaults
show_channel_urls: true
default_channels:
  - https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/main
  - https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/r
  - https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/msys2
custom_channels:
  conda-forge: https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud
  msys2: https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud
  bioconda: https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud
  menpo: https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud
  pytorch: https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud
  simpleitk: https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud

3. 安装tensorflow-gpu==1.14.0

第一次尝试：

pip install tensorflow-gpu==1.14.0 -i https://pypi.tuna.tsinghua.edu.cn/simple

找不到版本。原因是自己的python是3.8。

tensorflow1.14需要python3.7版本，而python3.8版本对应的是tensorflow2版本。

于是首先创建python3.7环境。

conda create -n audio python=3.7

conda activate audio

第二次尝试：

pip install tensorflow-gpu==1.14.0 -i https://pypi.tuna.tsinghua.edu.cn/simple

安装成功。但是import出错。

错误1:
TypeError: Descriptors cannot not be created directly.
If this call came from a _pb2.py file, your generated code is out of date and must be regenerated with protoc >= 3.19.0.
If you cannot immediately regenerate your protos, some other possible workarounds are:

1. Downgrade the protobuf package to 3.20.x or lower.
2. Set PROTOCOL_BUFFERS_PYTHON_IMPLEMENTATION=python (but this will use pure-Python parsing and will be much slower).

解决方法：
pip install protobuf==3.19.0

错误2:

_np_quint16 = np.dtype([(“quint16”, np.uint16, 1)])

解决方法：
pip install numpy==1.16.4

4. 其它包的安装
   中间运行项目的时候，发现少一些包，比如resampy，pandas，使用pip单独安装会安装最新版本，然后卸载numpy1.16.4，安装更新版本的，这样会导致tensorflow又会报错，所以需要找到合适的resampy和pandas版本。从网上没找到说明，就手动一直实验，不好弄。后来发现可以用下面的方法解决：

pip install numpy==1.16.4 resampy numba scipy pandas h5py
这样写一块就能限制resampy、numba、scipy的版本，让他们自动兼容
