dvc: AttributeError: module 'enum' has no attribute 'IntFlag'

Hi @Casyfill !

Do you have enum34 installed by any chance? You can check that with pip freeze | grep enum34. If you do, please remove it, it is known to cause issues in many packages.

pip uninstall -y enum34

I have the issue as well. Uninstallation of enum34 solved the issue. I am working in virtual environemnt with Python3.7. In my case the dependent is catboost.

$ pip show enum34   
Name: enum34
Version: 1.1.6
Summary: Python 3.4 Enum backported to 3.3, 3.2, 3.1, 2.7, 2.6, 2.5, and 2.4

i also have the same issue of error while working on pycharm i also tried to run pip uninstall enum34 command but it shows me that enum34 was not installed i dont know what to do i have pyhton 3.8 version please help by any other solution THANKS…

what

I have upgraded my python version to 3.7. It is working now. Thanks.

Hi @daskol !

Thanks for reporting this! Looks like catboost shouldn’t install enum34 in newer python versions: https://github.com/catboost/catboost/blob/6550fd5ef349acd08d021f8210e322201b169951/catboost/python-package/setup.py#L30 . It should probably be handled similar to how these guys have fixed it https://github.com/donnemartin/saws/commit/f109bc8f534905797ee44239cb766ea3de4ceb5d . We’ve looked for some kind of preemptive solution on our side, but looks like it should indeed be handled by projects that are actually using enum34.

hi. M having a similar issue but uninstalling unum34 doesn’t solve it, here is my traceback:

Traceback (most recent call last): File “run.py”, line 2, in <module> from wtforms import Form, StringField, TextAreaField, PasswordField, validators File “/home/leeuw/.local/lib/python3.5/site-packages/wtforms/init.py”, line 11, in <module> from wtforms import validators, widgets File “/home/leeuw/.local/lib/python3.5/site-packages/wtforms/validators.py”, line 9, in <module> import email_validator File “/home/leeuw/.local/lib/python3.5/site-packages/email_validator/init.py”, line 6, in <module> import dns.resolver File “/home/leeuw/.local/lib/python3.5/site-packages/dns/resolver.py”, line 32, in <module> import dns.flags File “/home/leeuw/.local/lib/python3.5/site-packages/dns/flags.py”, line 24, in <module> class Flag(enum.IntFlag): AttributeError: module ‘enum’ has no attribute ‘IntFlag’

I have tried to installed enum34 on all my pip instances available on my Synology system. /usr/bin/pip uninstall -y enum34 /usr/bin/pip2 uninstall -y enum34 /usr/bin/pip2.7 uninstall -y enum34 /volume1/@appstore/py3k/usr/local/bin/pip uninstall -y enum34 /volume1/@appstore/py3k/usr/local/bin/pip3 uninstall -y enum34

Always the same: WARNING: Skipping enum34 as it is not installed.

Any other suggestions?

Hi there. I am struggling as well and getting an error at class Modes(enum.IntFlag): AttributeError: module ‘enum’ has no attribute ‘IntFlag’

Any help is appreciated.

/volume1/@appstore/py3k/usr/local/lib/python3.5/enum.py Using Python executable: /volume1/@appstore/py3k/usr/local/bin/python3 Using Python version: 3.5.1 (default, Jan 29 2018, 14:18:59) [GCC 4.9.3 20150311 (prerelease)] Platform: Linux-3.10.105-x86_64-with-glibc2.3.4 PYTHONPATH: None

import sys import enum

def main(argv): print (‘Hello there’, sys.argv[1])

class Modes(enum.IntFlag): Listen = 1

print (‘Hello there’, sys.argv[1])

if name == name: main(sys.argv[1:])

This helped me:

I was able to fix this by adding enum34 = “==1.1.8” to pyproject.toml. Apparently enum34 had a feature in v1.1.8 that avoided this error, but this regressed in v1.1.9+. This is just a workaround though. The better solution would be for packages to use environment markers so you don’t have to install enum34 at all unless needed.

Life savers. Thanks. Was installing a GTFS parser and old tech was being hung up on something I don’t even remember installing.

I don’t have pip freeze per se, but I was able to reproduce it having the conda env below. Given that it just started to happen, I blame the last lib I installed - halo, but didn’t have a chance so far to check if I am correct
