Sampling FAQ
Common messages and situations on the screen during training sampling. Look them up by "what you see → meaning → what to do". At the end are a few rules to remember.
In short
- Footage recorded but not uploaded is wasted. Upload it the same day you record it.
- If a clip has gone missing, press N clips on this device › to find it.
- If an upload fails, press Upload All or Retry on the card once the network is back.
Entry and list
| What you see | Meaning | What to do |
|---|---|---|
| No Training Sampling entry on the left | Your company has not enabled the training platform | Ask your administrator |
| "Training platform not configured. Contact your administrator…" | Same as above | Ask your administrator. After it is enabled, press Re-check |
| "The list may be out of date (platform unreachable, using the last cache)" | The machine cannot reach the platform, so the operation tree may be old | Check the network. Once it is back, switch back to the "Capture" tab or press Refresh |
| An operation just created cannot be found in the tree | The list has not been updated yet | Press Refresh |
| Opening the sampling page sends you back to sign-in, and after signing in you are kicked out again | The operation you last selected was deleted on the platform, and older versions mistook this for an expired sign-in | Fixed in the current stable release; the machine automatically forgets deleted operations. If it still happens, ask a technician to check the machine version |
| "Select an operation on the left" | No operation selected yet | In the left column, tap down to the operation level |
| "Record a teaching video first" | This operation has no teaching video yet | Press Record teaching video and record and upload one first |
| "Your company has no global detection classes yet…" | The global class list is empty | Press Create global class, or ask a technician |
Recording and clips
| What you see | Meaning | What to do |
|---|---|---|
| No clips in the middle column, but I did record | The clips are under another capture target | Press N clips on this device › to find them, then press Go upload |
| "Change capture target? …N clips still to upload" | The current target has clips not uploaded | The clips are not lost. Go ahead and change; find and upload them later with "N clips on this device" |
| Orange "missing reference frames" after choosing mixed classes | Some parts have no separate part footage yet | Record a separate clip for each of those parts right away |
| "This clip is an intermediate format left by an interruption… cannot be played back (can be uploaded)" | A clip whose recording was interrupted | It cannot be watched but can be uploaded. If in doubt, delete it and record again |
| Clip corner tag "Not 16:9" or "Low resolution" | The imported video differs from the machine's camera | See "Import file" in Record footage |
| Footage looks blurry | The capture resolution is low | Ask a technician to set Settings › Display › Capture Resolution to 1920×1080 |
| "Cannot crop the picture while production is running" | Production is running | You can trim the start and end now; crop when idle |
| "Recording in progress. Leaving will stop the recording first" | You are leaving while recording | Press Cancel to keep recording, or confirm to leave (recording stops automatically) |
Upload
| What you see | Meaning | What to do |
|---|---|---|
| The card turns red, and History shows "Failed" or "Network error" | The network dropped during upload | Once the network is back, press Upload All again or Retry on the card. For a teaching video, press its button again |
| "Backend restarted; upload status lost. Upload again" | The machine restarted during upload | Press upload again |
| "Upload the footage first" | Some clips are not uploaded, or none has ever been uploaded | Press Go upload, then train after uploading |
| "A released SOP process's teaching video cannot be changed on the device…" | The machine version is too old to replace a released SOP process's video | Ask a technician to upgrade; newer versions use Replace released video. Or "Return to draft" on the platform |
Training, verification and calibration
| What you see | Meaning | What to do |
|---|---|---|
| "Training failed" | Something went wrong while the backend was learning | Press Train again. If it fails again, ask a technician |
| "Cannot verify a test model during production" | Production is running | End production, then verify |
| "Some classes have not been verified" | Some parts have never been recognized | Press Keep verifying to keep trying; if a part is not recognized, press Collect more |
| "Producing; stop production first" (Calibrate tab) | Production is running | Stop production, then calibrate |
| "None of the operations released on this device has a 'Length ratio' detection step" | The insertion check has not been set up on the platform, or not released | Ask a technician to set it up on the platform, have it reviewed and release it |
| "The two groups overlap" (Calibrate tab) | Good and bad pieces of this part cannot be told apart by measuring | Do not write back; ask a technician |
Notes
- Footage recorded but not uploaded is wasted. Upload it the same day; uploading needs the network.
- Footage not uploaded is not deleted automatically, but it takes up space; uploaded footage is cleaned up automatically. If too much piles up, the machine refuses new recordings. When it says space is low, delete what you do not need first. Use N clips on this device › now and then to check for anything you forgot to upload.
- Snapshots go into the training footage just like videos, and after upload you can see them in the footage on the training platform. Error samples go to "Hard samples" and are used only after a technician confirms them.
- Do not press Verify model, Release this version or Start calibration while someone else is producing.
- As long as an operation is recognized accurately, there is no need to train it again and again. Add footage only when the machine does not recognize well.
These actions cannot be undone on the machine
Remove, Sync to platform, Release this version, Write back to platform, Replace released video. Check carefully before pressing them.
