NameError: name 'gpu_mem_get_free_no_cache' is not defined

[rraminen]

The below error is from lesson3-camvid.ipynb notebook:

I could see that the definition of gpu_mem_get_free_no_cache() in fastai ( https://github.com/fastai/fastai/blob/master/fastai/utils/mem.py )

Is this module currently under development for fastai 2 or can I use it from fastai/utils/mem.py ?

You should use it from fastai utils for now.
