昇腾910使用记录

一. 压缩文件和解压文件

1. 压缩文件

tar -czvf UNITE-main.tar.gz ./UNITE-main/

2. 解压文件

tar -xvf ./UNITE-main/

二. CUDA更改为NPU

data['label'] = data['label'].cuda()
data['instance'] = data['instance'].cuda()
data['image'] = data['image'].cuda()

更改为

data['label'] = data['label'].npu()
data['instance'] = data['instance'].npu()
data['image'] = data['image'].npu()

三. 配置环境变量

1. 创建env.sh

touch env.sh

2. 打开env.sh

vi env.sh

3. 配置环境变量

# 配置CANN相关环境变量
CANN_INSTALL_PATH_CONF='/etc/Ascend/ascend_cann_install.info'
if [ -f $CANN_INSTALL_PATH_CONF ]; thenDEFAULT_CANN_INSTALL_PATH=$(cat $CANN_INSTALL_PATH_CONF | grep Install_Path | cut -d "=" -f 2)
elseDEFAULT_CANN_INSTALL_PATH="/usr/local/Ascend/"
fi
CANN_INSTALL_PATH=${1:-${DEFAULT_CANN_INSTALL_PATH}}
if [ -d ${CANN_INSTALL_PATH}/ascend-toolkit/latest ];thensource ${CANN_INSTALL_PATH}/ascend-toolkit/set_env.sh
elsesource ${CANN_INSTALL_PATH}/nnae/set_env.sh
fi
# 导入依赖库
export LD_LIBRARY_PATH=${LD_LIBRARY_PATH}:/usr/local/openblas/lib
export LD_LIBRARY_PATH=${LD_LIBRARY_PATH}:/usr/local/lib/
export LD_LIBRARY_PATH=${LD_LIBRARY_PATH}:/usr/lib64/
export LD_LIBRARY_PATH=${LD_LIBRARY_PATH}:/usr/lib/
export LD_LIBRARY_PATH=${LD_LIBRARY_PATH}:/usr/lib/aarch64_64-linux-gnu
# 配置自定义环境变量
export HCCL_WHITELIST_DISABLE=1
# log
export ASCEND_SLOG_PRINT_TO_STDOUT=0 # 日志打屏, 可选
export ASCEND_GLOBAL_LOG_LEVEL=3 # 日志级别常用 1 INFO级别; 3 ERROR级别
export ASCEND_GLOBAL_EVENT_ENABLE=0 # 默认不使能event日志信息

并输入

:wq!

4. 使用环境

source env.sh

猜测可能是没有开混合精度

五. 开启混合精度

1. 在构建神经网络前，我们需要导入torch_npu中的AMP模块

import time
import torch
import torch.nn as nn
import torch_npu
from torch_npu.npu import amp    # 导入AMP模块

2. 在模型、优化器定义之后，定义AMP功能中的GradScaler

model = CNN().to(device)
train_dataloader = DataLoader(train_data, batch_size=batch_size)    # 定义DataLoader
loss_func = nn.CrossEntropyLoss().to(device)    # 定义损失函数
optimizer = torch.optim.SGD(model.parameters(), lr=0.1)    # 定义优化器
scaler = amp.GradScaler()    # 在模型、优化器定义之后，定义GradScaler

3. 在训练代码中添加AMP功能相关的代码开启AMP

for epo in range(epochs):
for imgs, labels in train_dataloader:
imgs = imgs.to(device)labels = labels.to(device)with amp.autocast():outputs = model(imgs)    # 前向计算loss = loss_func(outputs, labels)    # 损失函数计算optimizer.zero_grad()# 进行反向传播前后的loss缩放、参数更新scaler.scale(loss).backward()    # loss缩放并反向传播scaler.step(optimizer)    # 更新参数（自动unscaling）scaler.update()    # 基于动态Loss Scale更新loss_scaling系数
