How to install RecBole on windows PyCharm? (package versions have conflicting dependencies error)

[alanjacob10]

Hi,

Does anybody know why i get the following error when trying to install recbole in PyCharm? :

Error occured:
`ERROR: Cannot install recbole==0.1.0, recbole==0.1.1, recbole==0.1.2 and recbole==0.2.1 because these package versions have conflicting dependencies.

Proposed solution:
Try to run this command from the system terminal. Make sure that you use the correct version of 'pip' installed for your Python interpreter located at 'C:\Users\AlanR\PycharmProjects\recboletest1\venv\Scripts\python.exe'.

Command Output:
Collecting recbole

Collecting colorlog==4.7.2

Using cached hyperopt-0.2.5-py2.py3-none-any.whl (965 kB)

The conflict is caused by:
recbole 0.2.1 depends on torch>=1.7.0
recbole 0.1.2 depends on torch>=1.6.0
recbole 0.1.1 depends on torch>=1.6.0
recbole 0.1.0 depends on torch>=1.6.0

To fix this you could try to:

1. loosen the range of package versions you've specified
2. remove package versions to allow pip attempt to solve the dependency conflict

ERROR: Cannot install recbole==0.1.0, recbole==0.1.1, recbole==0.1.2 and recbole==0.2.1 because these package versions have conflicting dependencies.
ERROR: ResolutionImpossible: for help visit https://pip.pypa.io/en/latest/user_guide/#fixing-conflicting-dependencies`

I tried updating pip, and also install recbole through commando promt but didn't seem to react to this. Still can't install in PyCharm.

Ps. Recbole support kindly helped me with another issue in another discussion, but do to too much memory power required by the algorithms I had to switch to a windows computer with more RAM and here this issue occured.

Sincerely,
Alan

It seems that you have pytorch < 1.6.0 on your Windows device, while RecBole 0.2.1 requires pytorch >= 1.7.0.

Upgrade your pytorch package and try again?

[alanjacob10]

Yes I tried this...
It gave the following error when trying to install through shell (didn't work in PyCcharm):

And apparently the latest version was already found on my windows.:

I cannot make sure if you install PyTorch on the correct environment...

Maybe you can open your PyCharm project, create a new .py file, run the following code

import torch
print(torch.__version__)

to check the PyTorch version on your PyCharm environment.

[alanjacob10]

What do you mean with installing to the correct enviroment? how do you do this?

I tried what you wrote but it didn't find any torch version.

Regards,
Alan

Hi Alan,

Maybe you can learn about how to configure a Python interpreter in a PyCharm project and install, uninstall, and upgrade packages in a PyCharm project firstly before installing recbole.
