怎么Could not find conda environment: python-study You can list all discoverable environments with `conda info --envs`.进入终端

2. 输入 `conda activate python-study`，这将激活名为 "python-study" 的 conda 环境。如果您在运行上述命令时收到错误消息 "Could not find conda environment: python-study"，这意味着 conda 环境 "python-...

e-study无法正常显示界面

### 回答1：如果e-study无法正常显示界面，可能有以下几种原因导致： 1. 网络连接问题：请检查您的网络连接是否正常。您可以尝试刷新网页或重新连接网络，看是否能解决问题。 2. 兼容性问题：某些网页可能对特定...

void MainClass::search(){ if(this->study->listLong() > 0){ cout << "请输入要查询学生的电话号或者姓名，输入“0”退出" << endl; string TNAME; cin >> TNAME; flushstd; if (TNAME == "0") { return; } if (strspn(TNAME.data(), "0123456789") == TNAME.length()) { //判断输入的是学号还是姓名 Study* temp = this->study->headerList(); while(temp->nextList() != nullptr){ //学号执行 temp = temp->nextList(); if (temp->studyPhone == TNAME) { // DIRECTORY(true); this->putstu(temp); return; } } } else { bool state = false; Study* temp = this->study->headerList(); while(temp->nextList() != nullptr){ //姓名执行 temp = temp->nextList(); if (temp->studyName == TNAME) { state = true; // DIRECTORY(true); this->putstu(temp); } } if (state == true) { return; } } cout << "没有此学生" << endl; return; }else{} cout << "无数据" << endl; return;

如果有学生信息，则打印提示信息，要求用户输入要查询的学生的电话号码或姓名，如果用户输入的是0，则直接退出查询。 2. 接下来，通过`strspn`函数和`if`语句来判断用户输入的是学生的电话号码还是姓名。如果是电话...

将['D:\PythonProject-Resnet\study\24.ClassifyLeaves_ImageFolder\classify-leaves\split\save\model.pth']去掉[]

1. 使用索引操作符[]：你可以使用索引操作符[]来获取列表中的元素。在这种情况下，你可以使用来获取列表中的第一个元素。例如： path = ['D:\PythonProject-Resnet\study\24.ClassifyLeaves_ImageFolder\classify-...
