python .exe 文件不会打开/运行

Question

我用 anaconda 作为解释器在 Visual Studio 代码中编写了一个 python 文件。我使用 pyinstaller 将文件转换为 exe，但是当我尝试打开 exe 时，cmd 窗口会闪烁打开一秒钟然后关闭。不知道为什么打不开我的程序应该从 HDF5 文件中读取并打印出用户请求的特定数据，它在 Visual Studio 代码中正是这样做的。我真的只需要一种方法，让它能够在未安装 python 的另一台计算机上由某人运行。

这是我的整个代码，我知道它可能很糟糕，因为我没有太多的 python 经验，但它可以在 Visual Studio 代码中工作：

import numpy as np
import h5py

print ("Make sure to move the HDF file to the folder where this program is located.")
valid = "valid"

#gets the file name and checks if file exists
while valid == "valid":
    filename = input("\nwhat is the name of the HDF file including the .hdf: ")
    try:
        with h5py.File(filename,"r") as hdf:
            path = hdf.get("/Results/Unsteady/Output/Output Blocks/Base Output/Unsteady Time Series/2D Flow Areas/Flow Area")
            break
    except IOError:
        print ("File not found")

#opens file
with h5py.File(filename,"r") as hdf:

    #navigates to file location
    path = hdf.get("/Results/Unsteady/Output/Output Blocks/Base Output/Unsteady Time Series/2D Flow Areas/Flow Area")
    path_items = list(path.items())

    #keeps running until user tells it to stop
    run = "y"
    while run == "y" or run == "Y" or run == "yes" or run == "Yes":

        #user input
        while valid == "valid":
            choice = input("\nWhich file would you like to get data from?  Depth, Face Shear stress, Face Velocity, or Water Surface: ")
            choice = choice.lower()
            if choice == "depth" or choice == "face shear stress" or choice == "face velocity" or choice == "water surface":
                break
            else:
                print ("Invalid")

        #checks the user input then converts the data set into a numpy array
        if choice == "depth":
            dataset = np.array(path.get("Depth"))
        if choice == "face shear stress":
            dataset = np.array(path.get("Face Shear Stress"))
        if choice == "face velocity":
            dataset = np.array(path.get("Face Velocity"))
        if choice == "water surface":
            dataset = np.array(path.get("Water Surface"))

        #gets the shape/size of the dataset
        shape = str(dataset.shape)
        shape = shape.replace("(","")
        shape = shape.replace(")","")
        shape = shape.split(",")
        timeAmount = shape[0]
        pointAmount = shape[1]
        timeAmount = int(timeAmount)
        pointAmount = int(pointAmount)
        timeAmount -= 1
        pointAmount -= 1
        print ("\nThis data set has",timeAmount,"time values and",pointAmount,"data values.")

        #user input
        while valid == "valid":
            time = input("\nEnter a single time step: ")
            try:
                int(time)
                break
            except ValueError:
                print ("Invalid")
        time = int(time)

        while valid == "valid":
            minR = input("\nEnter the first (smaller) value in a range of cell locations: ")
            try:
                int(minR)
                break
            except ValueError:
                print ("Invalid")
        minR = int(minR)

        while valid == "valid":
            maxR = input("\nEnter the second (larger) value in a range of cell locations: ")
            try:
                int(maxR)
                break
            except ValueError:
                print ("Invalid")
        maxR = int(maxR)

        #calculates all the numbers in the range between the two numbers
        rangeL = []
        while minR != maxR:
            rangeL.append(minR)
            minR += 1
        rangeL.append(maxR)

        #prints the value at each point
        count = 0
        for x in range(len(rangeL)):
            tempN = rangeL[count]
            tempV = dataset[time,rangeL[count]]
            print (str(tempN) + "," + str(tempV))
            count += 1

        #asks the user if they want to get more data
        run = input("\nWould you like to enter more parameters to get more/different data? (y/n): ")
        if run == "y" or run == "Y" or run == "yes" or run == "Yes":
            pass
        else:
            print ("Goodbye")
            break

Answer 1

可能是因为您的代码只有几个输出。这意味着程序非常快地执行这些行并最终关闭。在代码末尾请求输入。这应该使程序保持打开状态。

Answer 2

它对我有用。我使用 pyinstaller 命令：pyinstaller -F file_name.py。有用。不快速关闭并且还要求输入。
