ImportError run python project from Google Drive in Google Colab - tensorflow

Question

I mouth my Google Drive with Google Colab (follow the post by https://medium.com/deep-learning-turkey/google-colab-free-gpu-tutorial-e113627b9f5d)
!apt-get install -y -qq software-properties-common python-software-properties module-init-tools
!add-apt-repository -y ppa:alessandro-strada/ppa 2>&1 > /dev/null
!apt-get update -qq 2>&1 > /dev/null
!apt-get -y install -qq google-drive-ocamlfuse fuse
from google.colab import auth
auth.authenticate_user()
from oauth2client.client import GoogleCredentials
creds = GoogleCredentials.get_application_default()
import getpass
!google-drive-ocamlfuse -headless -id={creds.client_id} -secret={creds.client_secret} < /dev/null 2>&1 | grep URL
vcode = getpass.getpass()
!echo {vcode} | google-drive-ocamlfuse -headless -id={creds.client_id} -secret={creds.client_secret}
!mkdir -p drive
!google-drive-ocamlfuse drive
Then I place Tensorflow nmt into drive/colab/ (drive is google drive root directory.
I run the command in Colab Cell
!python drive/colab/nmt/nmt.py\
--attention=scaled_luong \
--src=src --tgt=tgt \
--vocab_prefix=drive/colab/data/vi-vi/vocab \
--train_prefix=drive/colab/data/vi-vi/small_train \
--dev_prefix=drive/colab/data/vi-vi/val \
--test_prefix=drive/colab/data/vi-vi/test \
--out_dir=drive/colab/data/vi-vi/nmt_attention_model \
--num_train_steps=12000 \
--steps_per_stats=100 \
--num_layers=2 \
--num_units=128 \
--dropout=0.2 \
--metrics=bleu
With error
/usr/local/lib/python3.6/dist-packages/h5py/__init__.py:36: FutureWarning: Conversion of the second argument of issubdtype from `float` to `np.floating` is deprecated. In future, it will be treated as `np.float64 == np.dtype(float).type`.
from ._conv import register_converters as _register_converters
Traceback (most recent call last):
File "drive/colab/nmt/nmt.py", line 31, in <module>
from . import inference
ImportError: cannot import name 'inference'
What should I do ?

Answer 1

It's happening because you are using relative import in nmt.py and your current directory is not the same as where nmt.py is located. And because of that python is not able to find the files. You can fix it by changing your directory to mnt using
%cd drive/colab/nmt/
and then running your command.
