java.awt.Dimensionandroid 的等效形式是什么？

我是 CMake 的新手，所以我总是更喜欢使用 CMake GUI。

我实际上是在设置点云库 (PCL)。但是，它需要一些其他依赖库，其中之一是 FLANN -> Git Link FLANN

到目前为止我所做的是：

1. 从链接下载源：Git Link FLANN
2. 创建了一个构建目录

3. 设置 CMake SOURCE 代码路径 - C:/PCL/flann-master

   设置 CMake Build 二进制文件路径 - C:/PCL/flann-master/build

4. 检查分组和高级选项
5. 配置

它给出了以下错误：

CMake Warning (dev) at CMakeLists.txt:17 (if):
  Policy CMP0054 is not set: Only interpret if() arguments as variables or
  keywords when unquoted.  Run "cmake --help-policy CMP0054" for policy
  details.  Use the cmake_policy command to set the policy and suppress this
  warning.

  Quoted …

我对 tensorflow 很陌生，我想清楚地知道，下面的命令有什么作用？

import tensorflow as tf
from tensorflow import keras
from tensorflow.keras import layers
import os

num_skipped = 0
for folder_name in ("Cat", "Dog"):
    print("folder_name:",folder_name) #folder_name: Cat
    folder_path = os.path.join("Dataset/PetImages", folder_name)
    print("folder_path:",folder_path) #folder_path: Dataset/PetImages/Cat
    for fname in os.listdir(folder_path):
        print("fname:",fname) #fname: 5961.jpg
        fpath = os.path.join(folder_path, fname)
        print("fpath:", fpath) #fpath: Dataset/PetImages/Cat/10591.jpg
        try:
            fobj = open(fpath, "rb")
            is_jfif = tf.compat.as_bytes("JFIF") in fobj.peek(10)
        finally:
            fobj.close()

        if not is_jfif:
            num_skipped += 1
            # Delete corrupted image
            os.remove(fpath)

print("Deleted %d images" % num_skipped)
