Hil*_*urn 2 python pandas pytorch
我有一个CSV文件,其中包含标题行以外的所有数字值。尝试构建张量时,出现以下异常:
Traceback (most recent call last):
File "pytorch.py", line 14, in <module>
test_tensor = torch.tensor(test)
ValueError: could not determine the shape of object type 'DataFrame'

这是我的代码:
import torch
import dask.dataframe as dd
device = torch.device("cuda:0")
print("Loading CSV...")
test = dd.read_csv("test.csv", encoding = "UTF-8")
train = dd.read_csv("train.csv", encoding = "UTF-8")
print("Converting to Tensor...")
test_tensor = torch.tensor(test)
train_tensor = torch.tensor(train)

使用pandas而不是DaskCSV解析会产生相同的错误。我也尝试dtype=torch.float64在对的调用中指定torch.tensor(data),但再次遇到相同的错误。
我想你只是失踪了 .values
import torch
import pandas as pd
train = pd.read_csv('train.csv')
train_tensor = torch.tensor(train.values)

强烈建议使用to_numpy较新版本的 pandasvalues
train_tensor = torch.tensor(train.to_numpy())
