Problems with pytmx

[Piethon]

I tried out what you said @metulburr and @michael1789 but it is not working.
Now I am getting this error:

Traceback (most recent call last):
  File "/Users/.../Desktop/MyRPG/main.py", line 5, in <module>
    from sprites import *
  File "/Users/.../Desktop/MyRPG/sprites.py", line 4, in <module>
    from tilemap import collide_hit_rect
  File "/Users/.../Desktop/MyRPG/tilemap.py", line 6, in <module>
    pytmx.load_pygame()
TypeError: load_pygame() missing 1 required positional argument: 'filename'

The code looks like this now:

import pygame as pg
#from pytmx.util_pygame import load_pygame
import pytmx
from settings import *

pytmx.load_pygame()

def collide_hit_rect(one, two):
    return one.hit_rect.colliderect(two.rect)

class TiledMap:
    def __init__(self, filename):
        tm = pytmx.util_pygame.load_pygame
        self.width = tm.width * tm.tilewidth
        self.height = tm.height * tm.tileheight
        self.tmxdata = tm = load_pygame(filename, pixelalpha=True) #load_pygame("outdoor.tmx")

    def render(self, surface):
        ti = self.tmxdata.get_tile_image_by_grid
        for layer in self.tmxdata.visible_layers:
            if isinstance(layer, pytmx.TiledTileLayer):
                for x, y, gid, in layer:
                    tile = ti(gid)
                    if tile:
                        surface.blit(tile, (x * self.tmxdata.tilewidth, y * self.tmxdata.tileheight))

    def make_map(self):
        temp_surface = pg.Surface((self.width, self.height))
        self.render(temp_surface)
        return temp_surface

In the sprites.py file I just imported that collide_hit_rect thing, because I need it there.
I don't know why it is not working.
I made a new map and didn't move any of the files.
Hope you guys can help me out.

Thanks. Happy New Year by the way. :-)
