!pip install detectron2 -f
https://dl.fbaipublicfiles.com/detectron2/wheels/cu102/torch1.7/index.html

i use this code for install detectron2, and i meet this error
ModuleNotFoundError: No module named 'iopath.tabular'

It's a pain to correctly pin versions down otherwise, getting that information from Pypi is not fun.

It would be helpful to (optionally) have remote path handlers display the progress bar when downloading files

The docs of PathManager.opena() suggest that async reading is supported:

But running the suggested code leads to the following error:

Are there plans to support async file reading? Thanks!

when i debug the code event_logger.py， it just goto the line “except ImportError:”

try:
from tmetry.simpleevent import SimpleEventRecord
from tmetry.writer import TmetryWriter

b_tmetry_available = True

except ImportError:
b_tmetry_available = False

We are using iopath in MMF library. Our CI tests are failing with this error from iopath library on Windows, Python 3.8 :

Hi, very recently, we are noticing in VISSL project that PathManager.exists("") evaluates to true which clearly seems like a bug. Can you please advice on this and if you think this is a bug or an intentional change?

Fatal Python error: init_sys_streams: can't initialize sys standard streams

This commit f4e103f introduces
from typing import Protocol which is only available after python 3.8. https://docs.python.org/3/library/typing.html#typing.Protocol

Please fix this as it has broken downstream projects that rely on iopath, e.g. https://github.com/facebookresearch/detectron2/runs/5100428039?check_suite_focus=true

In general, please revamp the open source CI and enable it so such issues can be caught: https://github.com/facebookresearch/iopath/blob/main/.circleci/config.yml

When using Detectron, I noticed this exception from the facebookresearch iopath package:

An exception occurred in telemetry logging.Disabling telemetry to prevent further exceptions.
Traceback (most recent call last):
  File "/opt/conda/envs/osml_models/lib/python3.11/site-packages/iopath/common/file_io.py", line 946, in __log_tmetry_keys
    handler.log_event()
  File "/opt/conda/envs/osml_models/lib/python3.11/site-packages/iopath/common/event_logger.py", line 97, in log_event
    del self._evt
        ^^^^^^^^^

I've fixed this exception locally by simply removing the call: handler.log_event().

This code isn't affecting execution, but it would be nice to clean up the output until a more permanent fix can be implemented.

The base class default is in the current user's homedir, which can be problematic in some Azure environments. We can improve things by defaulting to a more appropriate location.
