我有一个非常简单的数组,我想在其上运行ROC曲线分析.但首先,当我尝试使用命令将数据强制转换为因子类型时table[1]<-factor(table[1]),我得到了错误
Error in sort.list(y) : 'x' must be atomic for 'sort.list'
Have you called 'sort' on a list?
下面给出了数据中很少的样本行

class SBA (models.Model):
question = models.TextField(blank=False)
system = models.CharField(max_length=3, choices=pacscon.System.which_system)
case = models.ForeignKey('pacscon.Patient')
created = models.DateField(auto_now_add=True)
reference = models.TextField(blank=True)
def __unicode__(self):
return self.question
class Answer(models.Model):
id = models.AutoField(primary_key=True)
body = models.TextField()
correct = models.BooleanField(default=False)
sba = models.ForeignKey(SBA, null=True)
def __unicode__(self):
return self.body
admin.py看起来像这样:
from models import Answer, SBA, Mnemonic
#from django import forms
from django.contrib import admin
class AnswerInline(admin.StackedInline):
model = Answer
extra = 2
class SBAAdmin(admin.ModelAdmin):
fieldsets = (
(None, {
'fields': ('question', 'system', 'case', 'reference')
}),
) …我正在 CUDA GPU 上训练一个 CNN，它将 3D 医学图像作为输入并输出一个分类器。我怀疑 pytorch 中可能存在错误。我正在运行 pytorch 1.4.0。GPU 是“特斯拉 P100-PCIE-16GB”。当我在 CUDA 上运行模型时出现错误

MainWindow::MainWindow(QWidget *parent) :
QMainWindow(parent),
ui(new Ui::MainWindow)
{
ui->setupUi(this);
model = new QSqlTableModel(this);
model->setTable("staging");
model->select();
model->setHeaderData(0, Qt::Vertical, tr("ID"));
model->setHeaderData(1, Qt::Vertical, tr("Region"));
model->setHeaderData(2, Qt::Vertical, tr("T1"));
model->setHeaderData(3, Qt::Vertical, tr("N1"));
model->setHeaderData(4, Qt::Vertical, tr("M1"));
ui->tableView->setEditTriggers(QAbstractItemView::NoEditTriggers);
ui->tableView->setModel(model);
ui->tableView->showRow(1);
ui->tableView->resizeColumnsToContents();
}
我只想以这样的视图显示表格，即列显示为行，行显示为列。我搜索过谷歌等，但找不到任何简单的解决方案。提到了代理模型，但我不确定如何使用 QSqltablemodel 来实现它，在本例中它不使用数据方法，而是使用 model->select() 语句来立即填充整个模型。任何指导将不胜感激。
