AttributeError: 'str' object has no attribute 'decode'

[mctosima]

Hi, I just running the example code using MacOS 11.3.1, opencv-python 4.5.2.52 (also the headless), python 3.9.5 with PureThermal 2 and Lepton 2.5

from flirpy.camera.lepton import Lepton

cam = Lepton()
image = cam.grab()
print(image)
print(cam.frame_count)
print(cam.frame_mean)
print(cam.ffc_temp_k)
print(cam.fpa_temp_k)
cam.close()

The error showed AttributeError: 'str' object has no attribute 'decode'

Do I miss something ? I already installed all the package required. I also try to run this code but the result is same

import cv2
from flirpy.camera.lepton import Lepton

with Lepton() as camera:
    while True:
        img = camera.grab().astype(np.float32)

        # Rescale to 8 bit
        img = 255*(img - img.min())/(img.max()-img.min())

        # Apply colourmap - try COLORMAP_JET if INFERNO doesn't work.
        # You can also try PLASMA or MAGMA
        img_col = cv2.applyColorMap(img.astype(np.uint8), cv2.COLORMAP_INFERNO)

        cv2.imshow('Lepton', img_col)
        if cv2.waitKey(1) == 27:
            break  # esc to quit

cv2.destroyAllWindows()

Thank's for helping and sharing

Are you installing from git or from pypi? I think this issue was already corrected (it was due to a double decode), but it may not have reached pip yet. Try with an older version of Python e.g. 3.5 - this became an error with newer versions.

I'm getting a similar error, with Windows 10 and a Boson camera:

from flirpy.camera.boson import Boson camera = Boson() images = camera.grab() Traceback (most recent call last): File "", line 1, in File "C:\Program Files\Python37\lib\site-packages\flirpy\camera\boson.py", line 256, in grab self.setup_video(device_id) File "C:\Program Files\Python37\lib\site-packages\flirpy\camera\boson.py", line 208, in setup_video device_id = self.find_video_device() File "C:\Program Files\Python37\lib\site-packages\flirpy\camera\boson.py", line 146, in find_video_device self.logger.info("Device ID: {}".format(device_id)) AttributeError: type object 'Boson' has no attribute 'logger'

I installed flirpy through Pycharm. Is there a more up-to-date repository? Above, Git and PyPi were mentioned, but I didn't see which one had the freshest code. If there's not an easy fix, will try downgrading from 3.7 to 3.5.

Advice appreciated.

@planter01 try installing from git directly. This repository will always have the freshest code. This logging issues is fixed in the main branch.

That worked. Thanks very much!
