无法在keras(tensorflow)中使用model.predict() [英] can't manage to use the model.predict() in keras(tensorflow)

问题描述

背景:

我正在将Pycharm与Python 3.6配合使用(不使用较新的版本，因为我有一个不支持较新版本的python的库).

I'm using Pycharm with Python 3.6(not using a newer version because I have a library that doesn't support a newer version of python).

我为防病毒构建了一个ml模型并将其保存(试图将其保存为"anti_virus_model.h5"和文件夹)

I built a ml model for an anti-virus and saved it(tried saving it as 'anti_virus_model.h5' and as a folder)

我正在尝试为反病毒软件构建UI，所以我正在使用tkinter库.

I'm trying to build a UI for the anti-virus so I'm using the tkinter library.

问题: 我试图加载我的模型(非常确定它可以正常工作)并预测所选择的文件(将标头转换为矢量之后) 我导入了tensorflow和keras，但是pycharm似乎无法识别功能model.predict(pe). [pe是我的载体]

The problem: I tried to load my model(pretty sure it worked) and predict the file that was selected(after turning the header into a vector) I imported tensorflow and keras but the function model.predict(pe) doesnt seem to be recognized by pycharm. [pe is my vector]

这是我的代码:

from tkinter import *
from tkinter import filedialog
from tensorflow import keras

import vector_build
import tkinter as Tk
import tensorflow as tf



tf.keras.models.load_model('anti_virus_model.h5')

def browse_file():
    fname = filedialog.askopenfilename(filetypes=(("exe files", "*.exe"), ("exe files", "*.exe")))
    print(fname)
    pe = vector_build.encode_pe(fname)
    print(pe)
    print(keras.model.predict(pe))



root = Tk.Tk()
root.wm_title("Browser")
broButton = Tk.Button(master=root, text='Browse', width=80, height=25, command=browse_file)
broButton.pack(side=Tk.LEFT, padx=2, pady=2)

Tk.mainloop()

选择文件后出现的错误是:

(过程不会崩溃，我将其关闭了)

提前谢谢！

推荐答案

将问题重构为可以轻松测试的东西！在这里拥有一个成熟"的GUI程序并不是确保各种细节都能正常工作的最佳方法.

Refactor your problem to something you can easily test! Having a "full-fledged" GUI program here isn't the best way to make sure the various bits and pieces work as they should.

1. 您对同一事物进行了多次导入，包括*导入会混淆事物.
2. load_model()返回一个模型实例；您不会在任何地方使用它.

1. You have multiple imports of the same thing, including a * import which will confuse things.
2. load_model() returns a model instance; you aren't using that anywhere.

简化操作以将UI与实际的预测代码分开，您将获得易于测试的内容:

Simplifying things to separate the UI from the actual prediction code, you get something that's easily testable:

import tkinter as Tk
from tkinter import filedialog
from tensorflow import keras
import vector_build

model = keras.models.load_model("anti_virus_model.h5")


def predict_file(fname):
    print(fname)  # Debugging
    pe = vector_build.encode_pe(fname)
    print(pe)  # Debugging
    result = model.predict(pe)
    print(result)  # Debugging
    return result


def browse_file():
    fname = filedialog.askopenfilename(filetypes=(("exe files", "*.exe"),))
    result = predict_file(fname)
    # TODO: Do something with `result`


def ui_main():
    root = Tk.Tk()
    root.wm_title("Browser")
    broButton = Tk.Button(master=root, text="Browse", width=80, height=25, command=browse_file)
    broButton.pack(side=Tk.LEFT, padx=2, pady=2)

    Tk.mainloop()


if True:  # First make this branch work correctly,
    predict_file("C:/Windows/Calc.exe")
else:  # ... then switch to this.
    ui_main()
