Error message: variables needed for gradient computation has been modified by an inplace operation

[nauman46055]

Hello dear brother,
i am running condensenet and densent_LGC in pycahem IDE with Python 3.6.5 :: Anaconda, Inc. with following configurations:
dataset - cifar10
epochs - 200
bottleneck - 3
growth - 12-12-12
C=G=4
batch size = 64

i am getting this error exactly at 34th epoch every time. i have tried to remove 'inplace addition operations' and ' inplace=True' from Relu, but nothing has worked . Can you please help, how can it be fixed. Regards

Sorry for being late. Could you show me the command you use to train? The pytorch API changed a lot since 0.2, so I am planning to re-check the code recently to make sure it fits 0.4.
