So I want to read mutiple text file from my folder with followinh code but i encounter the PermissionError: [Errno 13] Permission denied, anyone know how should i modify my code so i can succesfully get my data from folder?

X_train = np.loadtxt('D:/Object/train(text)')
X_test = np.loadtxt('D:/Object/test(text)')

print("Shape of training set: {}".format(X_train.shape))
print("Shape of testing set: {}".format(X_test.shape))


def image_grid(D,H,W,cols=10,scale=1):
    """ display a grid of images
        H,W: Height and width of the images
        cols: number of columns = number of images in each row
        scale: 1 to fill screen
    """
    n = np.shape(D)[0]
    rows = int(math.ceil((n+0.0)/cols))
    fig = plt.figure(1,figsize=[scale*20.0/H*W,scale*20.0/cols*rows],dpi=300)
    for i in range(n):
        plt.subplot(rows,cols,i+1)
        fig=plt.imshow(np.reshape(D[i,:],[H,W]), cmap = plt.get_cmap("gray"))
        plt.axis('off')



H = 250
W = 250

This how my folder look like

example result

this is how i hope it came out
