笔记本型号是Redmi G2021，配置还凑活，5800H，16G, 3050Ti Laptop（4G VRAM)，相当一般的配置啦！不过自从英伟达更新了驱动，可以实现RAM充当显存，可训练以及使用的模型就多了很多啦，当然这种类似swap的方式性能还是有点损失的。不过，总比运行不起来强多啦！
数据准备
话说想做这件事许久啦，有时很好奇别人讲的是哪里话，又不好意思问？就萌生了个训练方言识别是哪里人的想法，当然，相比方言意思识别简单超多的还是。这里还是佩服国家队的中国电信，开源了30种方言的大语言模型。于是，我也决定利用开放的数据集训练个分类模型玩玩。
本来想用R-Torch的，发现自己处理的操作太多啦，主要是R语言深度学习真的不是主流。不小心发现了一个开箱即用的，于是，折腾起来：yeyupiaoling/AudioClassification-Pytorch
代码准备
就严格按照作者的python版本等进行的，没有例外，开源软件的版本兼容是令人一言难尽的，所以，能一致尽量完全一致！我是win11，不过git这种操作用的是WSL2进行的。我一般用WSL2操作windows下的目录，这样读写性能损失超多，只是不想文件删除后还不能释放空间（WSL2是个特殊虚拟机）
代码语言：javascript复制# 软件安装
conda create -n python=3.8
# pytorch等
conda install pytorch==1.13.1 torchvision==0.14.1 torchaudio==0.13.1 pytorch-cuda=11.6 -c pytorch -c nvidia
# mcls
python -m pip install macls -U -i https://pypi.tuna.tsinghua.edu.cn/simple
# 用的repo
git clone https://github.com/yeyupiaoling/AudioClassification-Pytorch.git
cd AudioClassification-Pytorch/
pip install .
# 齐活！
数据下载
经过选择，最终是用了这个KeSpeech，不过后面发现，我直接用的这个repo也是有个方言数据集3dspeaker_data可用的。不过下载一个已经用去几百G的空间，不想再下第二个啦！另外，碍于电脑配置，也用不了那么多数据，这里我还从里面节选了几分之一做训练呢！
测试和训练集的截取划分
我的数据准备过程比较傻瓜，直接用最基本的AI辅助编码写了两个脚本实现的，简单的说就是读取两个文本文件内容，建立两个字典，然后匹配，抽取前1200条数据，生成训练集，再抽取200多用于测试集。明显数据是偏少的。
代码语言：javascript复制# every class first 1000
i = 0
dic = {}
fout = open('D:/Projects/dialect/KeSpeech/Metadata/train_audio_path', 'w')
with open('D:/Projects/dialect/KeSpeech/Metadata/phase1.utt2subdialect', 'r') as f:
for line in f:
dialect = line.split('t')[1]
if dialect not in dic.keys():
dic[dialect] = 1
else:
dic[dialect] = 1
if dic[dialect] > 250 and dic[dialect] <1200:
fout.write(line)
fout.close()
dic_file = dict()
with open('D:/Projects/dialect/KeSpeech/file.txt') as f1:
for line in f1:
if line.endswith('wavn'):
fi = line.strip().split('/')[3]
dic_file[fi] = line.strip()
# print(fi,dic_file[fi])
# 训练和测试集一个脚本生成的，改了下名字，按说该整个函数的
fout2 = open('D:/Projects/dialect/KeSpeech/Metadata/test_list.txt', 'a')
with open('D:/Projects/dialect/KeSpeech/Metadata/test_audio_path', 'r') as f2:
for line in f2:
file_name = line.split('t')[0] '.wav'
if file_name in dic_file.keys():
fout2.write(dic_file[file_name] 't' line.strip().split('t')[1] 'n')
else:
print(file_name)
# break
fout2.close()
# label file生成
labels_dict = {0: 'Mandarin', 3: 'Northeastern', 2: 'Jiang-Huai',
3: 'Southwestern', 4: 'Jiao-Liao', 5: 'Beijing', 6: 'Zhongyuan',
7: 'Ji-Lu', 8: 'Lan-Yin'}
with open('D:/Projects/dialect/AudioClassification-Pytorch/dataset/label_list.txt', 'w', encoding='utf-8') as f:
for i in range(len(labels_dict)):
f.write(f'{labels_dict[i]}n')
这里还对标签做了替换，因为标签只能是数字。
代码语言：javascript复制sed -i s/'Mandarin'/0/g test_list.txt
sed -i s/'Northeastern'/1/g test_list.txt
sed -i s/'Mandarin'/0/g s/'Northeastern'/1/g s/'Jiang-Huai'/2/g test_list.txt
sed -i s/'Jiang-Huai'/2/g test_list.txt
sed -i s/'Southwestern'/3/g test_list.txt
sed -i s/'Jiao-Liao'/4/g test_list.txt
sed -i s/'Beijing'/5/g test_list.txt
sed -i s/'Zhongyuan'/6/g test_list.txt
sed -i s/'Ji-Lu'/7/g test_list.txt
sed -i s/'Lan-Yin'/8/g test_list.txt
完成这些，把文件放入新建的dataset文件夹，就可以愉快地训练啦，可以断点续训练的哦！点赞！
训练
特征提取
这是第一步，耗时并不多python extract_features.py --configs=configs/cam .yml --save_dir=dataset/features
漫长的训练
前后大概花了三天时间，每个两到三个小时的样子。也是一条命令的事！python train.py
评估效果
虽然初次训练结果不好，至少，成功获得了人生第一个语音分类模型，还是极开心的，感谢作者！
