No module named 'request' even after it is already there while running "Facebook AI Performance Evaluation Platform"

Question

I searched a lot and tried many of the SQ solutions but nothing helped me here... can someone check what exactly I messed up with?

My Python3 is installed in the directory here /usr/local/Cellar/python/3.7.0/

In my .bashrc I have added

export PYTHONPATH=$PYTHONPATH:/Users/swapnil.kotwal/Library/Python/3.7/lib/python/site-packages

Also, .bash_profile have

source ~/.bashrc alias python=python3 export PATH="/usr/local/bin:/usr/local/opt/node@10/bin:$PATH"

My Below command also works fine

$ python -c "import requests; print (requests.__version__)" 2.20.0

And other things are as below

But, when I ran FAI-PEP https://github.com/facebook/FAI-PEP

using command benchmarking/run_bench.py -b specifications/models/caffe2/shufflenet/shufflenet.json

I got error as below

$ benchmarking/run_bench.py -b specifications/models/caffe2/shufflenet/shufflenet.json
Traceback (most recent call last):

    import requests
ImportError: No module named requests

what is the output of `which pip3`? Also, you seem to execute the script as an executable. Is the interpreter in the shebang line is `/usr/bin/python`? — DeepSpace, Nov 01 '18 at 09:04

Please check where requests gets installed. Then check whether python is searching for the library in this directory.

In order to see where requests is installed, you can use the following pip command

pip list

compare How do I find the location of my Python site-packages directory? . In case the Location column is empty, the library was installed to the default directory.

And to see the directories in which python is searching for libraries you can use

print(__import__('sys').path)

In case requests is installed in a directory python is not looking in, I suggest reading these question: Permanently add a directory to PYTHONPATH , Install a Python package into a different directory using pip?

Also check that your python script is not executed in a virtual environment (virtualenv) where the package is not installed/available https://docs.python-guide.org/dev/virtualenvs/.

sys.path is ```['', '/usr/local/Cellar/python/3.7.0/Frameworks/Python.framework/Versions/3.7/lib/python37.zip', '/usr/local/Cellar/python/3.7.0/Frameworks/Python.framework/Versions/3.7/lib/python3.7', '/usr/local/Cellar/python/3.7.0/Frameworks/Python.framework/Versions/3.7/lib/python3.7/lib-dynload', '/Users/swapnil.kotwal/Library/Python/3.7/lib/python/site-packages', '/usr/local/lib/python3.7/site-packages']``` – Swapnil Kotwal Nov 01 '18 at 09:19
Can you find a requests folder with an \_\_init\_\_.py file in it in any of these directories? If no, please try installing the requests library to one of the given locations. If yes, is it working if you cd to the directory containing the requests folder in a shell, open python and execute the command "import requests"? – quant Nov 01 '18 at 09:30
I ```cd /usr/local/Cellar/python/3.7.0/Frameworks/Python.framework/Versions/3.7/lib/python3.7/site-packages/requests``` and ran ```pathon3``` and then ```import requests``` it worked... I think I need to add python3 *permanently* if yes how or best way I should go ? – Swapnil Kotwal Nov 01 '18 at 09:36
use import sys; sys.path.append("/usr/local/Cellar/python/3.7.0/Frameworks/Python.framework/Versions/3.7/lib/python3.7/site-packages") in your script before line 18 – quant Nov 01 '18 at 09:36
there could be too many files having ```request``` dependency. Can I add python3 for all scripts? I removed all python related entries from my ```.bash_profile``` files – Swapnil Kotwal Nov 01 '18 at 09:37
Sure the howto was already included in my answer from the very beginning https://stackoverflow.com/questions/3402168/permanently-add-a-directory-to-pythonpath you need to include the directory /usr/local/Cellar/python/3.7.0/Frameworks/Python.framework/Versions/3.7/lib/python3.7/site-packages since it is where the library is installed. However you only have /usr/local/Cellar/python/3.7.0/Frameworks/Python.framework/Versions/3.7/lib/python3.7 in your path ... – quant Nov 01 '18 at 09:39
