Cannot install crafter

[geoleva]

I'm trying to get DREAMER v3 working, but can't get all dependencies to install. I'm using >> pip install crafter or with specific version 1.8.2, and getting the following error (I was able to install version 1.8.1, but then got the error in using yaml when trying to do load):

I am using pip (23.3.1), python (3.9), and setuptools (69.0.1). After >> pip install crafter, I get this error:

note: This error originates from a subprocess, and is likely not a problem with pip.

same problem here. Unable to get it installed with pip. Only way is to install it manually or use it raw. Even then though it's unable to install crafter.

Could you try running pathlib.Path('README.md').read_text() from an interactive python interpreter in the repository root? Maybe pathlib does not fully support Windows?

Hi Danijar,

It indeed looks like that's the problem.

In the interactive python terminal I did the following:
import pathlib pathlib.Path('README.md').read_text()

I got the following output:

Traceback (most recent call last): File "<stdin>", line 1, in <module> File "C:\Users\nickdv\AppData\Local\Programs\Python\Python311\Lib\pathlib.py", line 1058, in read_text with self.open(mode='r', encoding=encoding, errors=errors) as f: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "C:\Users\nickdv\AppData\Local\Programs\Python\Python311\Lib\pathlib.py", line 1044, in open return io.open(self, mode, buffering, encoding, errors, newline) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ FileNotFoundError: [Errno 2] No such file or directory: 'README.md'

I have fixed the problem by using os instead of Pathlib:

import setuptools
import os

# Read the content of README.md
with open('README.md', 'r', encoding='utf-8') as file:
    long_description = file.read()

setuptools.setup(
    name='crafter',
    version='1.8.3',
    description='Open world survival game for reinforcement learning.',
    url='http://github.com/danijar/crafter',
    long_description=long_description,
    long_description_content_type='text/markdown',
    packages=['crafter'],
    package_data={'crafter': ['data.yaml', 'assets/*']},
    entry_points={'console_scripts': ['crafter=crafter.run_gui:main']},
    install_requires=[
        'numpy', 'imageio', 'pillow', 'opensimplex', 'ruamel.yaml',
    ],
    extras_require={'gui': ['pygame']},
    classifiers=[
