Error in importing utils or contrib

1

Hi everyone I just got started with pyro (deep markov model:
https://github.com/pyro-ppl/pyro/blob/dev/examples/dmm/polyphonic_data_loader.py) and unfortunately I cannot find a way to properly run the code.

indeed concerning the polyphonic data loader script i get the following import errors:

  • from pyro.contrib.examples.util import get_data_directory

same problem with the line

  • from torch._utils import ExceptionWrapper

any idea how to solve them?

2

can you post your python, pytorch, pyro versions and also the error message? make sure you’re using the release versions of everything

Hi sure,

sorry for the delay
python: 3.6.8
pytorch: 1.14.0
pyro: 1.16.4

and the error is :

ImportError Traceback (most recent call last)

ImportError: cannot import name ‘ExceptionWrapper’

NOTE: If your import is failing due to a missing package, you can
manually install dependencies using either !pip or !apt.

you installed the wrong pyro.

Hi, thank you for the answer,
I m working on google colab and to install it I used the
!pip3 install pyro-ppl

which one should i use then?

the correct version is 3.0.1?
