Finding you need to install `google-cloud-storage ` in `from google.cloud import storage`

[aguschin]

In some complex cases MLEM can have problems finding what to install. This happens pretty rarely AFAIK, but please upvote and leave a comment if you hit this problem so we can set a priority to investigate and fix.

Example:

$ pip install google-cloud-storage

(see https://cloud.google.com/storage/docs/reference/libraries)

from mlem.api import save
from google.cloud import storage

def f():
    storage

save(f, "storage")

print(storage.__name__)

which prints google.cloud.storage

saved metafile:

artifacts:
  data.pkl:
    hash: 0c3e2cfa007c4e8e25039367c68a29e4
    size: 277
    uri: storage
model_type:
  io:
    type: pickle
  methods:
    __call__:
      args: []
      name: __call__
      returns:
        type: unspecified
  type: callable
object_type: model
requirements:
- module: google
  package_name: google-api-core

last lines should have been something like:

- module: google.cloud.storage
  package_name: google_cloud_storage

Rn we use this:

>>> from importlib_metadata import packages_distributions
>>> packages_distributions()['box']
['python-box']

but in such cases as in the first comment, it breaks:

In [10]: pd = packages_distributions()

In [11]: for k in pd:
    ...:     if len(pd[k]) != 1:
    ...:         print(k, pd[k])
    ...:
