Enviroment to run this code

[ccu1tn]

Dear author:
Could you provide the environment to run this code?
Many errors in the channel.py and JSCCOFDM_model.py files as follows.

this error is at the channel.py file, I tried to fix it by dividing 2. But other results will be wrong.
x = x.view(N, self.opt.P, self.opt.S*(self.opt.M+self.opt.K)//2, 2)

Please help me.
My environment is:
conda 23.7.4
torch-2.0.1+cu118-cp38-cp38-win_amd64.whl
