problem and error in using pyorc

[amirdastgheib]

How did you install pyopenrivercam (mamba / conda or pip)

[pip]

What is the problem?

[I was using pyorc 0.5.2 and yesterday I updated the pyorc and since then I am getting error for getting the first frame. The code:

uncomment line below if you want to view coordinates interactively

%matplotlib notebook video_file = r'C:\Users\amerecosystem\Desktop\Amir\TU GRAZ\LSPIV\Field Work\Oberwolz\26-09-2023\Videos\Digital Camera\DSC_1380.MOV' video = pyorc.Video(video_file, start_frame=0, end_frame=1) # we only need one frame frame = video.get_frame(0, method="rgb")

plot frame on a notebook-style window

f = plt.figure(figsize=(10, 6)) plt.imshow(frame)

The error: AttributeError Traceback (most recent call last) Cell In[2], line 4 1 # uncomment line below if you want to view coordinates interactively 2 # %matplotlib notebook 3 video_file = r'C:\Users\amerecosystem\Desktop\Amir\TU GRAZ\LSPIV\Field Work\Oberwolz\26-09-2023\Videos\Digital Camera\DSC_1380.MOV' ----> 4 video = pyorc.Video(video_file, start_frame=0, end_frame=1) # we only need one frame 5 frame = video.get_frame(0, method="rgb") 7 # plot frame on a notebook-style window

AttributeError: module 'pyorc' has no attribute 'Video' and also I install again by: !pip install git+https://github.com/localdevices/pyorc.git and I got this error: IndexError Traceback (most recent call last) Cell In[3], line 4 2 get_ipython().run_line_magic('matplotlib', 'notebook') 3 video_file = r'C:\Users\amerecosystem\Desktop\Amir\TU GRAZ\LSPIV\Field Work\Oberwolz\26-09-2023\Videos\Digital Camera\DSC_1380.MOV' ----> 4 video = pyorc.Video(video_file, start_frame=0, end_frame=1) # we only need one frame 5 frame = video.get_frame(0, method="rgb") 7 # plot frame on a notebook-style window

How can we reproduce this? (What steps trigger the problem? What parameters are you using for processing? Include screenshots. If you are having issues processing a video, if possible include a copy of your dataset uploaded on Dropbox, Google Drive, or other)

is my problem clear?

I have tried to reproduce your problem with the same pip install command but cannot reproduce it. Can you try the following:

• activate your virtual envrionment (if you have any)
• run the following pip install --upgrade --no-deps --force-reinstall pyopenrivercam

then try your first lines of code again.

Ok Thank you for your help.

Did this work? Please let me know so I can close the issue.

I did so and at the same time I changed the videos folder to a complete different address and it works for now. Thank you.
