Thank you very much.
(1)The index information for net.parameters() is “Cannot find reference ‘parameters’ in (input:Any,…),kwargs:dict)->Any”
(2) The index information for “.Adadelta” is “Cannont find reference ‘Adadelta’ in  ini  .pyi”.
I find the /usr/local/lib/python3.6/dist-packages/dis-packages/torch/optim/  ini  .pyi, The code is
from .sgd import SGD as SGD
from .adam import Adam as Adam
from . import lr_scheduler as lr_scheduler
there is no Adadelta in the file. So, if my version is incomplete or not? I tred to install the torch by two ways: in the Pycharm intall the package, and in terminal input “sudo pip3 install torch”. The result is the same.
And for the net.parameters() problem, I guess if there need define a method for the parameters in my Network. In the before version, there is no need, but now I donnot know.
Despite the index information in pyCharm, but there is no warining or error during running. But yestoday, I trid to train the Network, the result implys there is no any improvement of my Network, so I doubt that the absent optimizer and the parameters() method.
Thank you very much. I do my best to solve the problem, but my knowledge for the pytorch is too little to do that. Please help me. Thank you again.
