can someone help me

Beata · August 20, 2019, 6:03pm

Hi Maz,

Can I ask you to contact us and send the files which my colleague Rhéa mentioned above?

We would need more details to efficiently resolve the issue you are experiencing.

Thanks in advance!

Yuri_Shendryk2 · August 26, 2019, 3:35pm

Hi Beata,

I have exactly the same problem as Maz:

[Error]: ClusterProcessing: Not enough initialized photos

[Error]: Generating tiles failed!

[Error]: \>\>\>Generating tiles\<\<\< failed with error (failed to run a step!)!

[Error]: \>\>\>Generating tiles\<\<\< failed with error (failed to run a step!)!

Followed by:

[Warning]: Warning w9020: GDAL Error \<4\> N:/Altum/Mareeba/Pix4d/20190311\_G1\_120m/1\_initial/project\_data/thumbnails/0007SET\_001\_IMG\_0358\_3\_512.jpg: No such file or directory

For whatever reason Pix4D is looking for images that start with ‘0007SET_’ (which is the name of the folder with the original imagery), while the actual images in the thumbnails folder don’t have this prefix. Any ideas?

Cheers,

Yuri

Beata · August 20, 2019, 6:05pm

Why not post the solution here so we don’t have to take the time to submit ticket? Seems like that makes more work for Pix4d too.

momtanu.chakraborty · August 20, 2019, 6:06pm

Hi Tyler, pdfs or doc files cannot be attached here which is why we ask you to write tickets. We are working towards a better solution for the community.

After the question has been solved through the ticketing system, we try to update the results here if the user got in touch with us. It would be also great if all our community users post their solutions here after it has been solved through support. Have a great day! Hope you understand

vivek2231 · September 6, 2019, 1:12am

I too am getting these errors as mentioned above. Was a solution found? I tried to contact tech support from, the link posted by Rhea, but it says page does not exist. Please advice.

Pix4D_Alumni_MV · September 6, 2019, 12:20pm

Hi Vivek,

The link has been restored.
Please attach your Quality Report and Log file if you want us to have a look on your project.

Best,

vivek2231 · September 7, 2019, 10:58pm

Hi Marco,

Yes, I will do that shortly. I was wondering if you know what the actual cause of warning w9020 was? for me it says the following “GDAL Error <1> latitude or longitude exceeded limits”. This is particularly frustrating in that I would expect multiple errors down the processing line due to this.

Cheers,
Vivek

eugene.farrell · October 26, 2019, 10:13am

Why will you not post the fix? I have emailed the support team too with same problem.

software4 · January 19, 2020, 7:34am

I have same issue, could you please tell me how to solve it!

Matthias_Siewert · February 5, 2020, 4:48pm

Is there any solution to this by now?

asosebee · February 28, 2020, 5:10pm

Anything discovered?I have a project that needs processing.

ikevanc · April 13, 2020, 8:15pm

I had a similar problem when the images were on a removable SSD. When I moved the images and project to an internal drive, warnings/errors went away. Removable SSDs have more R/W errors and it seems Pix4D does not retry a couple times.
