ImportError: cannot import name 'ReadTimeoutError'

[snowman2]

Pins:

botocore>=1.12.89,<1.13.0
s3transfer>=0.2.0,<0.3.

Just started happening today:

from boto3.s3.transfer import create_transfer_manager
File "/var/runtime/boto3/s3/transfer.py", line 129, in <module>
from s3transfer.manager import TransferConfig as S3TransferConfig
File "/var/task/s3transfer/manager.py", line 21, in <module>
from s3transfer.utils import get_callbacks
File "/var/task/s3transfer/utils.py", line 27, in <module>
from botocore.exceptions import ReadTimeoutError
ImportError: cannot import name 'ReadTimeoutError'

This pin seems to work (probably a looser version exists that works as well):

boto3==1.9.87
botocore==1.12.83

Can you share the specific version of botocore, s3transfer, and boto3 that were causing those issues for you? I tried a few options, but they're all working for me:

Using the version ranges you've provided:

$ pip install 'botocore>=1.12.89,<1.13.0'
$ pip install 's3transfer>=0.2.0,<0.3.'
$ python -c "from boto3.s3.transfer import create_transfer_manager"

With the oldest versions in the range:

$ pip install botocore==1.12.89 s3transfer==0.2.0 boto3
$ python -c "from boto3.s3.transfer import create_transfer_manager"

That ReadTimeoutError exception was added in botocore 1.11.0, so there shouldn't be an issue with a version range of botocore>=1.12.89,<1.13.0.

It also fail with AWS Lambda python 2.7 botocore==1.10.74 boto3==1.7.74

Comparing utils.py with download.py and init.py, the later import ReadTimeoutError from botocore.vendored.requests.packages.urllib3.exceptions instead of botocore.exceptions.

Not sure - it didn't show up in the build logs. By all means it doesn't make sense with the pins. Must be an underlying pin and something pip is doing when resolving dependencies.

I am seeing this issue as well and I am running the following versions

boto3==1.7.70
botocore==1.10.82
s3transfer==0.2.0

This is the stack trace that is failing. This just recently started happening. I noticed above that it was mentined that this exception ReadTimeoutError was added in 1.11.0 but if that is the case why am I getting the errors using 1.10.82?

  File "/.../venv/lib/python3.6/site-packages/s3transfer/manager.py", line 21, in <module>
    from s3transfer.utils import get_callbacks
  File "/.../venv/lib/python3.6/site-packages/s3transfer/utils.py", line 27, in <module>
    from botocore.exceptions import ReadTimeoutError
ImportError: cannot import name 'ReadTimeoutError'

Updating my botocore to 1.11.0 has solved the issue for me, however I am not sure why I was required to upgrade locally yet on our qa and production instances it is still running 1.10.82 without any issues.
