mathematical operations not available when using torch in eclipse

[brimb]

I am a new bie in pytorch but got issues using pytorch on eclipse. basic mathematical operations like torch.log, torch.add, torch.FloatTensor, etc are not available. However, if I use jupyter notebook these work perfectly well. Please has anyone encountered this problem and how could it be solved. Solving this problem would help me advance really well on my work as I have been stock for weeks.

Thank you in advance.
