!$final_v2e_command gives error about v2e HOT 9 CLOSED

from v2e.

Thanks for responding. I just tried the following v2e command and still gives error.

The Final v2e command:
v2e -i /content/v2e_tutorial_video.avi -o /content/v2e-output --overwrite --unique_output_folder false --dvs_h5 events.aedat --dvs_aedat2 None --dvs_text None --no_preview --dvs_exposure duration .033 --input_frame_rate 30 --input_slowmotion_factor 1 --disable_slomo --auto_timestamp_resolution false --pos_thres 0.2 --neg_thres 0.2 --sigma_thres 0.03 --cutoff_hz 30 --leak_rate_hz 0.1 --shot_noise_rate_hz 5 --dvs346

**ERROR:**v2ecore.emulator:Output file exception "Unable to create file (unable to lock file, errno = 11, error message = 'Resource temporarily unavailable')" (maybe you need to specify a supported DVS camera type?)

@yazidoudou18 feels like the HDF5 is trying to create a file but it couldn't.

Can you try a dummy example something like

import h5py

file = h5py.File("my_new_file", "w")

and see if this triggers any errors. Also, the path of the result folder, does it allow you to write files?

@duguyue100 The example was able to produce a file without triggering any errors. However, the 'final_v2e_command' was not able to output any files and caused the same errors.

Thank you, Tobi. I have not yet set up the v2e environment. All the errors I have encountered so far are based on using v2e in Google Colab.

I just tried the below command and it run to completion with the significant warning that the IIR lowpass filter is definitely not accurate for default cutoff of 300 Hz

v2e -i input/tennis.mov -o output/tennis --overwrite --unique_output_folder false --dvs_h5 events.h5 --dvs_aedat2 None --dvs_text None --no_preview --dvs_exposure duration .033 --input_frame_rate 30 --input_slowmotion_factor 1 --disable_slomo --auto_timestamp_resolution false --pos_thres 0.2 --neg_thres 0.2 --sigma_thres 0.03 --cutoff_hz 30 --leak_rate_hz 0.1 --shot_noise_rate_hz 5 --dvs346

Note that this was in the cloned local v2e env, not the colab workspace.
