Two different versions of 'screen_ocr' are downloaded during pip install #3

Closed LexiconCode closed 3 years ago

LexiconCode commented 3 years ago

Update The underlying issue 'screen_ocr' downloaded twice with 2 different versions. screen-ocr-0.1.0 is installed not screen_ocr-0.1.1 despite 0.1.1 downloaded 1st. I suspect this is a PIP issue than the screen-ocr package.

pip 21.1.2 from c:\users\mainlaptop\appdata\local\programs\python\python39\lib\site-packages\pip (python 3.9)

Installing from GitHub from zip pip install -e .[winrt] everything works as expected.

Original Issue

I originally tried from the readme python -m screen_ocr No module named screen_ocr.__main__; 'screen_ocr' is a package and cannot be directly executed

I tried executing the contents of __main__ in an editor and received the following.

Traceback (most recent call last):
  File "c:\Users\Main\Desktop\screen_ocr.py", line 1, in <module>
    import screen_ocr
  File "c:\Users\Main\Desktop\screen_ocr.py", line 3, in <module>
    ocr_reader = screen_ocr.Reader.create_quality_reader(radius=10000)
AttributeError: partially initialized module 'screen_ocr' has no attribute 'Reader' (most likely due to a circular import)
import screen_ocr

ocr_reader = screen_ocr.Reader.create_quality_reader(radius=10000)

results = ocr_reader.read_nearby(screen_coordinates=(0,0))
print(results.as_string())

I think the second issue is caused by naming your test script screen_ocr.py. Try naming it something else.

I'm not sure why python -m screen_ocr isn't working. I just tested it myself and it works. Are you sure you've upgraded to the latest version of the package? Perhaps this is caused by the above issue as well, if you're running the command from the directory with your screen_ocr.py script.

Yes that solved Partially initialized module 'screen_ocr' To test completely removed python (including modules) from my test environment on the laptop. I originally was on my desktop.

Reinstalled python 3.9.5 64-bit:

How ever not did not fix python -m screen_ocr.

I see that screen-ocr-0.1.0 is installed not screen_ocr-0.1.1.

Whats going on with pip? Looks as if screen_ocr is downloaded as screen-ocr-0.1.1 then screen_ocr-0.1.0. pip 21.1.2 from c:\users\mainlaptop\appdata\local\programs\python\python39\lib\site-packages\pip (python 3.9)

LexiconCode commented 3 years ago

I'm not sure what's going on with pip but installing the package locally works as expected. Given that I've tried this in a completely fresh system this is especially strange. However unless someone else reports the same thing I will consider this issue closed.

wolfmanstout commented 3 years ago

I plan to take a closer look when I have time. Probably a bug on my end.

wolfmanstout commented 3 years ago

Hmm, I couldn't reproduce it using a venv but on the other hand I was surprised how out of date screen-ocr was. I just pushed new versions of both screen-ocr (so that the module can be run as described in the readme) and gaze-ocr.
