Using Admanager Python API within a Colab Notebook

Question

I am trying to get the Google AdManager API to work into a Colab notebook.

Following the instructions here I have managed to create my own configuration YAML file, uploading it into the Colab notebook and executing the basic call to the NetworkService service. It all goes well and behaves as expected, returning the expected network name and ID.

Then I try to add some more requests like this and I get this error message:

FileNotFoundError                         Traceback (most recent call last)
    /usr/local/lib/python3.6/dist-packages/googleads/common.py in LoadFromStorage(path, product_yaml_key, required_client_values, optional_product_values)
        279   try:
    --> 280     with open(path, 'rb') as handle:
        281       yaml_doc = handle.read()


FileNotFoundError: [Errno 2] No such file or directory: '/root/googleads.yaml',

During handling of the above exception, another exception occurred:

GoogleAdsValueError                       Traceback (most recent call last)
<ipython-input-14-ed9b34dcaa81> in <module>()

     28   main(ad_manager_client)

/usr/local/lib/python3.6/dist-packages/googleads/ad_manager.py in LoadFromStorage(cls, path)
    202     return cls(**googleads.common.LoadFromStorage(
    203         path, cls._YAML_KEY, cls._REQUIRED_INIT_VALUES,
--> 204         cls._OPTIONAL_INIT_VALUES))
    205 
    206   def __init__(self, oauth2_client, application_name, network_code=None,

/usr/local/lib/python3.6/dist-packages/googleads/common.py in LoadFromStorage(path, product_yaml_key, required_client_values, optional_product_values)
    282   except IOError:
    283     raise googleads.errors.GoogleAdsValueError(
--> 284         'Given yaml file, %s, could not be opened.' % path)
    285 
    286   try:

GoogleAdsValueError: Given yaml file, /root/googleads.yaml, could not be opened.

And this despite the fact that the same yaml file uploaded in the folder of the notebook (content/googleads.yaml) works perfectly well with the first request.

Any help appreciated.

Thanks!

PS: just to let you know, I am still in my infancy with Python.

It would be easier to help you if you included a minimal repro notebook showing what worked and what didn't. Guessing in the dark, though: the thing that worked had extra code that looks in the current directory for the YAML file, while the thing that didn't doesn't. Simplest fix might be to create a symlink like:

!ln -s /content/googleads.yaml /root/googleads.yaml
