ModuleNotFoundError: No module named 'imutils'

[majurgens]

Hi

I've followed all the instructions on your module page and did not get any errors. I went to run encode.py and I get:

Traceback (most recent call last):
  File "encode.py", line 5, in <module>
    from imutils import paths
ModuleNotFoundError: No module named 'imutils'

I found some other similar post in the forum but they are slightly different and I don't really know anything about python so I'm not really sure how the import system works and why it can't find imutils.

Is there a particular version of python you need. From the forum I saw someone was running python 3.7. I also have python 2.7.16 and python3 v3.7.3

If I pip uninstall imutils, it seems to want to remove it from /home/pi/.local/lib/python2.7/site-packages/imutils/. This does not quite seem right.

I went through the install again and used pip3 instead of pip eg pip3 install COMPONENT and now it works.

I think this is a documentation issue

I think I might have resolved this with the last pull since I updated the documentation around pip vs pip3 - can you please check what I have written and if it makes sense close this issue?

[nischi]

Which pull do you mean?

[majurgens]

The one that you just approved and where I updated the documentation

[nischi]

hmm i think this is not 100% correct what you written there. pip is for phyton 2 and pip is for python 3 as i know. so if you have installed python 3 you should use pip3. so maybe you change the text a little bit?

[majurgens]

I'm pretty sure that it is correct. I installed a Fedora machine that did not have pip installed and only had python3 installed. After installing python3-pip, the pip command was available and was the same as pip3

[user@testmachine ~]# pip
-bash: pip: command not found
[user@testmachine ~]# pip3
-bash: pip3: command not found
[user@testmachine ~]# dnf install python3-pip

Okay strange. Then i do not understand why it was not working. Maybe another problem. Will keep the issue open for a while. Let see if somebody else has the same issue.

[majurgens]

It was not working originally because I had 2 versions of python installed and when I followed the instructions to use pip, it was using python2 instead of python3.

[nischi]

Ah okay, but still a strange behaviour. I will extend the readme
