一，準(zhǔn)備數(shù)據(jù)

imdb數(shù)據(jù)集的目標(biāo)是根據(jù)電影評論的文本內(nèi)容預(yù)測評論的情感標(biāo)簽。

訓(xùn)練集有20000條電影評論文本，測試集有5000條電影評論文本，其中正面評論和負面評論都各占一半。

文本數(shù)據(jù)預(yù)處理較為繁瑣，包括文本切詞，構(gòu)建詞典，編碼轉(zhuǎn)換，序列填充，構(gòu)建數(shù)據(jù)管道等等。

此處使用gensim中的詞典工具并自定義Dataset。

下面進行演示。

#5，構(gòu)建管道
from torch.utils.data import Dataset,DataLoaderclass ImdbDataset(Dataset):def __init__(self,df):self.df = dfdef __len__(self):return len(self.df)def __getitem__(self,index):text = self.df["text"].iloc[index]label = torch.tensor([self.df["label"].iloc[index]]).float()tokens = torch.tensor(text_pipeline(text)).int() return tokens,labelds_train = ImdbDataset(dftrain)
ds_val = ImdbDataset(dfval)
dl_train = DataLoader(ds_train,batch_size = 50,shuffle = True)
dl_val = DataLoader(ds_val,batch_size = 50,shuffle = False)
for features,labels in dl_train:break

二，定義模型

使用Pytorch通常有三種方式構(gòu)建模型：使用nn.Sequential按層順序構(gòu)建模型，繼承nn.Module基類構(gòu)建自定義模型，繼承nn.Module基類構(gòu)建模型并輔助應(yīng)用模型容器(nn.Sequential,nn.ModuleList,nn.ModuleDict)進行封裝。

此處選擇使用第三種方式進行構(gòu)建。

三，訓(xùn)練模型

訓(xùn)練Pytorch通常需要用戶編寫自定義訓(xùn)練循環(huán)，訓(xùn)練循環(huán)的代碼風(fēng)格因人而異。

有3類典型的訓(xùn)練循環(huán)代碼風(fēng)格：腳本形式訓(xùn)練循環(huán)，函數(shù)形式訓(xùn)練循環(huán)，類形式訓(xùn)練循環(huán)。

此處介紹一種較通用的仿照Keras風(fēng)格的類形式的訓(xùn)練循環(huán)。

該訓(xùn)練循環(huán)的代碼也是torchkeras庫的核心代碼。

# 評估
model.evaluate(dl_val)
100%|██████████████████████████████████████████████████████████████████████████████████████████████████████████████████████████████████████| 100/100 [00:01<00:00, 50.26it/s, val_acc=0.836, val_loss=0.395]{'val_loss': 0.39490113019943235, 'val_acc': 0.8357999920845032}

五，使用模型

def predict(net,dl):net.eval()with torch.no_grad():result = nn.Sigmoid()(torch.cat([net.forward(t[0]) for t in dl]))return(result.data)
y_pred_probs = predict(net,dl_val)
y_pred_probs

tensor([[0.9372],[1.0000],[0.8672],...,[0.5141],[0.4756],[0.9998]])

六，保存模型

#模型權(quán)重已經(jīng)被保存在了ckpt_path='checkpoint.'
net_clone = Net()
net_clone.load_state_dict(torch.load('checkpoint'))
<All keys matched successfully>
