PyCharm 2017: Remote debugging using remote interpreter doesn't work

I set up a remote interpreter and verified that I can run a script using the remote interpreter. Console output in the Run window looks like this:

ssh://freddy@192.168.178.60:22/usr/bin/python -u /home/freddy/workspace/tensorflow/models/inception/inception/imagenet_train.py --num_gpus=2 --batch_size=64 --num_sub_batches_per_batch=2 --train_dir=/tmp/imagenet_train --data_dir=/media/data/imagenet

The script 'imagenet_train.py' works fine.

However when I start the remote interpreter in debug mode, nothing happens:

1. I do not get a debug window

2. The debug icon remains gray after I clicked it to start debugging

There is no other output what so ever.

The only clue I have is (and this already shows at start up of Pycharm) a error message in the 'Python console' :

Error:Failed to add remote port forwarding

Any input to how to get my remote debugging going is appreciated.

Ok, so I found my solution. The error in my Python console let me to it ('Error:Failed to add remote port forwarding').

On my Ubuntu server I had to set  'AllowTcpForwarding yes' in the ssh config file (/etc/ssh/sshd_config) and restart the SSH daemon.

Would be good if PyCharm would give an error when I start debugging that something is wrong, I didn't get any output at all.

I don't know what's going on, but when I have this problem, I simply restart `(File -> Invalidate Caches / Restart ...)` PyCharm and it was fixed :)

Restarting always helps :)

@huangbiubiu

Have you tried setting AllowTcpForwarding to yes as mentioned above?
