无法导入包文件（未命名模块...）（Python）

Question

I am receving this error while I am try to run the code (from CMD):

ModuleNotFoundError: No module named 'numbers.hog'; numbers is not a package

Here is the hog.py file code...

from skimage import feature

class HOG:
    def __init__(self, orientations = 9, pixelsPerCell = (8, 8),
        cellsPerBlock = (3, 3), normalize = False):
        self.orienations = orientations
        self.pixelsPerCell = pixelsPerCell
        self.cellsPerBlock = cellsPerBlock
        self.normalize = normalize

def describe(self, image):
    hist = feature.hog(image,
    orientations = self.orienations,
    pixels_per_cell = self.pixelsPerCell,
    cells_per_block = self.cellsPerBlock,
    normalize = self.normalize)

    return hist

...and the main ( train.py ) which return the error.

from sklearn.svm import LinearSVC
from numbers.hog import HOG
from numbers import dataset
import argparse
import pickle as cPickle


ap = argparse.ArgumentParser()
ap.add_argument("-d", "--dataset", required = True,
    help = "path to the dataset file")
ap.add_argument("-m", "--model", required = True,
    help = "path to where the model will be stored")
args = vars(ap.parse_args())


(digits, target) = dataset.load_digits(args["dataset"])
data = []

hog = HOG(orientations = 18, pixelsPerCell = (10, 10),
    cellsPerBlock = (1, 1), normalize = True)

for image in digits:
    image = dataset.deskew(image, 20)
    image = dataset.center_extent(image, (20, 20))

    hist = hog.describe(image)
    data.append(hist)

model = LinearSVC(random_state = 42)
model.fit(data, target)

f = open(args["model"], "w")
f.write(cPickle.dumps(model))
f.close()

I don't uderstand why it gives me error on module package. numbers is a package, why it don't import it as well (as it seems) ?

UPDATE: tried to put from .hog import HOG and then execute from CMD..It prints:

No module named '__main__.hog'; '__main__' is not a package

Is it crazy ? hog.py is in the main package together with the other files. As you can see, it also contains HOG class.... Can't understand.. Some one can reproduce the error ?

In the IDE console it prints:

usage: train.py [-h] -d DATASET -m MODEL
train.py: error: the following arguments are required: -d/--dataset, -m/--model

This should be correct as soon as it is executed in IDE because the program MUST run in CMD.

UPDATE 2: for who is interested, this is the project https://github.com/VAUTPL/Number_Detection

Answer 1

Change from numbers.hog import HOG to from hog import HOG and
change from numbers import dataset to import dataset .

You are already in the "numbers" package so you don't have to precise it again when you import it.
When you type from numbers import dataset , Python will look for a package numbers (inside the actual package) that contains a dataset.py file.

If your train.py was outside the numbers package then you have to put the package name ( numbers ) before.

Answer 2

Important numbers is a python standard package https://docs.python.org/2/library/numbers.html

Check if you are not really importing that package or rename your package to a more specific name.

Also:

It might looks like python doesnt recognize your package.

Open a python shell and write:

import sys
print sys.path

Check if your number path is there.

If it's not there you have to add it.

sys.path.insert(0, "/path/to/your/package_or_module")

Answer 3

Your train.py file is already in the package "numbers", so you don't have to import numbers.

Try this instead:

from hog import HOG

I saw in comment that it gives you "error (red line)".
Can you be more precise, because I don't see errors there.
