我正在尝试在Kotlin中编写我的应用程序,但是当我在EXTRA_NOTE打开EditNoteActivity时,我无法将其转换为非null类型并且app force停止.

任何帮助都得到高度赞赏

码:

class EditNoteActivity : AppCompatActivity() {

var note: Note? = null

private val editNote: TextView? = null

private val fabdrwble: Boolean? = null
private val notesData: MutableList<Note>? = null
private var databaseHelper: DatabaseHelper? = null

private val save: Boolean? = null
private var saveButton: FloatingActionButton? = null
private val tint: ColorStateList? = null

internal var mRowId: Long? = null

internal var spinner: Spinner? = null
internal var spinnertext: String? = null

internal var fav: Int = 0 …

我是 Tensorflow 和机器学习的新手，并使用 Tensorflow 和我的自定义输入数据尝试了 CNN。但我收到下面附加的错误。

数据或图像大小为 28x28，带有 15 个标签。我没有在这个脚本或错误中得到 numpy reshape 的东西。

非常感谢帮助。

    directories = [d for d in os.listdir(data_directory)

    labels = []
    images = []
    for d in directories:
        label_directory = os.path.join(data_directory, d)
        file_names = [os.path.join(label_directory, f) 
                      for f in os.listdir(label_directory) 
                      if f.endswith(".jpg")]

    return images, labels
