Labelimg: Building labelImg (Python3 and Qt5) on Fedora

[heis2201]

• OS:: Fedora 28
• PyQt version: Python 2.7.15 and Python 3.6.5

I would need help getting the latest labelImg up and running on my machine.
I couldn't find a linux binary of the latest version, and unfortunately I was not able to build/execute the sources provided.

Here is some output of my attempt to use pip3 to install labelImg (I ran the command without sudo before but of course it failed because of missing rights to write to /usr):

florian@t440-f25: ~/labelimg/labelImg $ sudo pip3 install labelImg
WARNING: Running pip install with root privileges is generally not a good idea. Try `pip3 install --user` instead.

Some other questions:

• Am I supposed to run it using pyhton 2?

• What are the requirements/dependencies on a Fedora system to successfully build labelImg?

• Where can I get support?

It looks like the "Get from PyPI" install instructions are out of date, thanks for bringing that to our attention.

In the meantime, I recommend building labelImg from source. Can you elaborate on the issues you faced when you attempted to do so?

Other questions:

• I find that labelImg actually works smoother with Python3 and Qt5

• I haven't tried running it on Fedora, but I can't imagine that it's very different from the Ubuntu setup

• The only place atm is here

[heis2201]

I actually managed to build labelImg from source. Here is what I did/had to do.

1. ) Install required packages: sudo dnf install qt5 python-qt5 python3-lxml
   2.) Clone github repo: git clone https://github.com/tzutalin/labelImg (git was installed)
   3.) cd labelImg
   4.) make qt5py3
   pyrcc5 -o resources.py resources.qrc

5.) python3 labelImg.py throws an error:

Traceback (most recent call last):
  File "labelImg.py", line 15, in <module>
    from PyQt5.QtGui import *
ModuleNotFoundError: No module named 'PyQt5'

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "labelImg.py", line 24, in <module>
    import sip
ModuleNotFoundError: No module named 'sip'

So, PyQt5 is missing. I used the pip3 command to install it. I should have maybe tried to use dnf to find the package (have heard that using pip/pip3 can cause hiccups for dnf later)

6.) $pip3 install PyQt5 --user

Finally I am able to execute the build:

7.) python3 labelImg.py

It works just fine. Install process is a bit different from the Ubuntu installation since packages have different names...
