Numpy返回“ TypeError：'float'对象无法解释为整数”

Question

这是我的代码：

<form [formGroup]="form" (ngSubmit)="submitSelectedCheckboxes()">
  <label formArrayName="receivedSummons" *ngFor="let summon of form.controls.receivedSummons.controls; let i = index">
    <input type="checkbox" [formControlName]="i">
  </label>
  <div *ngIf="!form.valid">At least one order must be selected</div>
  <br>
  <button [disabled]="!form.valid">submit</button>
</form>

Answer 1

len(a)/width将返回浮点数

尝试len(a)//width

更好的是，您可以使用-1作为第一个索引，np会为您计算

np.reshape(a,(-1,width))
