__init__() 收到意外的关键字参数“gpus”

Question

我正在尝试使用 pytorch 来进行生成人工智能。如该视频所示： https://www.youtube.com/watch ?v=_pIMdDWK5sc

我导入所有内容，如图所示：

import os

import torch
import torchvision
import torch.nn as nn
import torch.optim as optim
import torch.nn.functional as F
import torchvision.datasets as datasets
import torchvision.transforms as transforms
from torch.utils.data import DataLoader, random_split
from torchvision.datasets import MNIST

import matplotlib.pyplot as plt

import pytorch_lightning as pl


random_seed = 42
torch.manual_seed(random_seed)

BATCH_SIZE=128
AVAIL_GPUS = min(1, torch.cuda.device_count())
NUM_WORKERS=int(os.cpu_count() / 2)

但是当我运行训练器时：

trainer = pl.Trainer(max_epochs=20, gpus=AVAIL_GPUS)
trainer.fit(model, dm)

它向我显示了错误：

__init__() got an unexpected keyword argument 'gpus'

Answer 1

使用 trainer = pl.Trainer(max_epochs=20,accelerator="auto")
