no module named 'boltons'

[bwanaaa]

navigated to correct folder and tried this:

fsdl-text-recognizer-project/lab2_sln$ python text_recognizer/datasets/emnist_dataset.py

python emnist_dataset.py 
Traceback (most recent call last):
  File "emnist_dataset.py", line 10, in <module>
    from boltons.cacheutils import cachedproperty
ModuleNotFoundError: No module named 'boltons'

How can I install this project without pipenv?

[bwanaaa]

BTW, I installed pipenv and ran the recommeded command

pipenv run python text_recognizer/datasets/emnist_dataset.py

and got the same error.

I did

pip install cacheutils

installed the above library but it has no 'cachedproperty'

[bwanaaa]

and yes, I also did
pip install boltons
so that pip freeze shows

boltons==19.1.0
cachetools==3.1.1
cacheutils==0.1.1
certifi==2019.3.9
six==1.12.0
w3lib==1.20.0

and I still get

pipenv run python text_recognizer/datasets/emnist_dataset.py
Traceback (most recent call last):
  File "text_recognizer/datasets/emnist_dataset.py", line 10, in <module>
    from boltons.cacheutils import cachedproperty
ModuleNotFoundError: No module named 'boltons'

However if I start a python shell at the command line

Python 3.7.3 | packaged by conda-forge | (default, Mar 27 2019, 23:01:00) 
[GCC 7.3.0] :: Anaconda, Inc. on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> from boltons.cacheutils import cachedproperty
>>> 

So clearly, boltons is installed in my conda environment and is seen. However pipenv does not respect that. simply running
python text_recognizer/datasets/emnist_dataset.py

works.

BTW, can you add a requirements.text file to the github project so I dont have to guess which packages are needed.

@bwanaaa see the readme.md in the root folder. From project root run: pipenv install --dev
