Tibor Kiss updated BEAM-1546:
-----------------------------
Description:
Python SDK currently supports Python-2.7 only.
apache_beam package's init uses named component attribute
(sys.version_info.*major*) to bail if unsupported Python is used.
The named component based version was introduced in Python 2.7 thus
if one uses older Python version (e.g. 2.6) an AttributeError will be thrown:
{noformat}
Traceback (most recent call last):
File "apache_beam/examples/complete/autocomplete_test.py", line 22, in
<module>
import apache_beam as beam
File "/Users/tiborkiss/workspace/beam/sdks/python/apache_beam/__init__.py",
line 69, in <module>
if sys.version_info.major != 2:
AttributeError: 'tuple' object has no attribute 'major'
{noformat}
To fix this problem the {{sys.version_info.major}} should be replaced by
{{sys.version_info[0]}}.
was:
Python SDK currently supports Python2.7 only.
There are two shortcomings with the version check/enforcement:
1) apache_beam package's init uses named component attribute
(sys.version_info.*major*) to bail if unsupported Python is used.
The named component based version was introduced in Python 2.7 thus
if one uses older Python version (e.g. 2.6) an AttributeError will be thrown:
{noformat}
Traceback (most recent call last):
File "apache_beam/examples/complete/autocomplete_test.py", line 22, in
<module>
import apache_beam as beam
File "/Users/tiborkiss/workspace/beam/sdks/python/apache_beam/__init__.py",
line 69, in <module>
if sys.version_info.major != 2:
AttributeError: 'tuple' object has no attribute 'major'
{noformat}
To fix this problem the {{sys.version_info.major}} should be replaced by
{{sys.version_info[0]}}.
2) The Python interpreter & pip definition in pom.xml defines that {{python2}}
& {{pip2}} should be used. Users with multiple Python interpreters installed
might end up having python2 and pip2 pointing to their 2.6 installation.
Calling out {{python2.7}} and {{pip2.7}} explicitly would help to resolve this
problem.
