pyGPs code problem

[pygauss10]

(**English is not my native language; please excuse typing errors.)
I just installed a site package pyGPs(via 'pip install pyGPs', you can also download from https://github.com/marionmari/pyGPs), and after I try to run to ensure that it was correctly installed, Some problems occured: 'pyGPs\__init__' and 'pyGPs\Core\__init__' these two files said that the errors are from each other, and file 'pyGPs\Core\gp' can not run either. I try to find and search through Google but I cant found what is wrong with them:
pyGPs\__init__:

1 2 3 4 5 6 7 8

from __future__ import absolute_import import Optimization import Validation import GraphExtensions from Core import * from Core.gp import *   __all__ = ['Optimization', 'Validation', 'GraphExtensions', 'Core']

Error:

    import gp

pyGPs\Core\__init__:

pyGPs\Core\gp:

ModuleNotFoundError: No module named 'Core'

The first two errors said that no module named 'gp', but there is a module name gp; and the third error said that no module named 'Core', still there is a module name Core. So I wonder what are they talking about, should I reinstall them or there is something I miss in my site package? My objective is to run the file without error
(my python version is 3.8.3)

It is unclear what exactly you are running after doing the install. You should not be trying to run those files directly, but should be importing pyGPs into your script.

As an example, this file should run without error.

1 2	import pyGPs print("import successful")

Output:
$ python test.py
import successful

If that works okay, you should be able to call the pyGPs functions from within your script.

I see some differences between the behavior of the package and the documentation. I wonder if the code has undergone some updates and the documentation hasn't kept up?

One of the examples suggests that this should work:

1 2 3

import pyGPs import numpy as np model = pyGPs.GPR()      # specify model (GP regression)

But it doesn't. I was able to get it to work (and the demo to draw data) by making the following modifications:

1 2 3 4

import pyGPs import pyGPs.Core.gp import numpy as np model = pyGPs.Core.gp.GPR()      # specify model (GP regression)

I try to do what you said, and I found some strange things:

1 2	import pyGPs print("import successful")

and it shows

Error:
Traceback (most recent call last):

  File "C:\Users\elatm\.spyder-py3\temp.py", line 9, in <module>
    import pyGPs

  File "C:\Users\elatm\anaconda3\lib\site-packages\pyGPs\__init__.py", line 2, in <module>
    import Optimization

ModuleNotFoundError: No module named 'Optimization'

So I check the place where it is wrong:

1 2 3 4 5 6 7 8

from __future__ import absolute_import import Optimization import Validation import GraphExtensions from Core import * from Core.gp import *   __all__ = ['Optimization', 'Validation', 'GraphExtensions', 'Core']

and the error is

Error:
Traceback (most recent call last):

  File "C:\Users\elatm\anaconda3\lib\site-packages\pyGPs\__init__.py", line 2, in <module>
    import Optimization

  File "C:\Users\elatm\anaconda3\lib\site-packages\pyGPs\Optimization\__init__.py", line 2, in <module>
    import scg

ModuleNotFoundError: No module named 'scg'

I go check the error place

1 2 3 4

from __future__ import absolute_import import scg import minimize import conf

but it turns out that the script above is correct(no error)
When I go back to the first script, same error occur again, and the error occur in the second script changes
the second script:

1 2 3 4 5 6 7 8

from __future__ import absolute_import import Optimization import Validation import GraphExtensions from Core import * from Core.gp import *   __all__ = ['Optimization', 'Validation', 'GraphExtensions', 'Core']

the error changes to

Error:
Traceback (most recent call last):

  File "C:\Users\elatm\anaconda3\lib\site-packages\pyGPs\__init__.py", line 3, in <module>
    import Validation

  File "C:\Users\elatm\anaconda3\lib\site-packages\pyGPs\Validation\__init__.py", line 2, in <module>
    import valid

ModuleNotFoundError: No module named 'valid'

Then I run the script 'valid':

1 2	from __future__ import absolute_import import valid

the script is correct, and all of these become an error cycle: go back to first script, encounter error in first script, check second script(another error occur), run file(the file runs without error),go back to first script again...
It will finally output successfully

Output:
import successful

but it requires lots of 'fixing', and can't run with the only script open:

1 2	import pyGPs print("import successful")

I can't import pyGPs without having to open all the other files, is this a normal situation? If not, does the version matters or the installation isn't correct?

I just reinstall pyGPs agian and test it and I can import pyGPs right now. Then I remember I changed some script inside pyGPs in order to make them run independently(which means nothing), that may be the reason that the errors occur. Bowlofred I thank for your help.

I have the same thought, the documentation might not be updated for a long time so that some of the demo scripts can run, but some can't. They just have to be changed manually.
