Ever get an error message that says “Object arrays cannot be loaded when allow_pickle=false”? It’s a frustrating message that seems to pop up at the most inconvenient times. The good news is, there are some ways you can fix this problem and avoid it in the future!
Protect your code with the allow_pickle option, which is enabled by default. This will prevent any errors in your data from occurring. You can find this setting under “Settings” -> “Data Settings”.
If you want to limit who has access to a table that contains object arrays, change the permissions of said user/group so they are only granted Read Access permission for that particular table and nothing else (see the below screenshot). – Save all files before exiting Modify Data Source or Quota Manager — these tools have been known to cause Object Arrays Errors!
* **What do I do if I already had an error message? ** You might be stuck restarting your whole computer but you can also fix the problem by deleting a file. Disable allow_pickle in “Settings” -> “Data Settings”.
– Head back to your Quota Manager or Modify Data Source tool and delete one of the tables with an object array (see screenshot below) which might have caused this error message. You’ll then be able to save any changes you’ve made so far!
* **How do I know if my project has no Object Arrays? ** If all these steps were followed, your data is safe from these errors! Otherwise, check out our article on [Object Arrays](/blog/object-arrays/) for more information.
A common cause for receiving an Error Message: Object Arrays is that your computer’s python environment does not have the right libraries. If you are using Windows, this could be because there isn’t a Python installation on your machine or that it doesn’t contain the right modules for data science work and pandas in particular.
* **How do I know if my project has no Object Arrays? ** In Quota Manager, check to see if all of these tables with an object array (see screenshot below) exist in your database: `tablename_objectarray` . If all these steps were followed, your data is safe from these errors! Otherwise, check out our article on [Object Arrays](/blog/object-arrays/) for more information.
* **How can I fix my project if the object arrays are missing or corrupted? ** If you have backups, load your data from there. Otherwise, we recommend going through these steps:
– Export and save all of your data as CSV files in Quota Manager > Data > Export to CSV Files
Delete your database using SQLite Database Browser (this will delete any tables with `tablename_objectarray`)
Import this default SQL file into a new SQLite database on Windows and Linux: `sql/default.SQL` , replace “mydb” with whatever is appropriate for your installation’s name of choice. This restores everything but does not include any updates made since March 2017. For Mac, SQLite Studio includes a default database with the same name.
* **How do I know if object arrays are missing or corrupted? ** Object arrays can be displayed in Quota Manager > Data as “Unknown” for data type and “Missing file system path.” This may indicate that your backups have been lost, you’re using an older version of Quota Manager that doesn’t support them (Quota Manager Version 22), or they were deleted because there was corruption on disk. If this is the case, we recommend exporting and saving all of your data from Quota Manager as CSV files before deleting any tables with `tablename_objectarray` in its name to avoid losing updates made since March 2017. Alternatively, you could export data to a CSV file and then import it into another table.
* **How can I fix corrupted object arrays? ** Contact our customer success team at [email protected] with the name of your database, what Quota Manager version you are using, and any other relevant information about corruption issues on disk for example: “I found this error message in my Terminal when trying to use `sqlite`, could someone give me advice?” They will be able to advise how best to proceed based on their experience.

Numbering Content: How to Number Lists, Bulleted Points, Quotes, Etc. in Long-Form Content The following are guidelines for numbering lists of items as well as quotes within long forms of content that do not fit into a one sentence list (bullets). If you would like more information about using number systems other than Arabic numerals please email [email protected] with subject line “What languages does ITE support?”
* **Arabic Numbers – 0 through infinity (eastern) [or] Western Alphabet Letters A through Z (western)

If you would like more information about using number systems other than Arabic numerals please email [email protected] with subject line “What languages does ITE support?”
The first set of numbers or letters should be at the beginning of the paragraph, before quoted text, and then spaced by two commas from each subsequent letter/number. For example:
“This is an interesting point to think about,” she said in her article entitled “How to Make Change Happen.” She continued on with these thoughts: “Many people think that their individual actions are too small to have an impact. But as the proverb goes, ‘It takes one person to start a revolution,'”
* **Bulleted Lists – when constructing lists of items within long-form content it is important to use semantically correct language and text formatting so your audience can understand what you’re trying to say. For example:
” for bulleted list headers: *”bullet points should be consistently formatted across all levels.”*
Do not capitalize the first letter in each bullet point (unless they form sentences) or indent bullets based on level; instead, space by two commas between them. For example:
Point One Point Two
Point Three Point Four
* **Bulleted Lists – when constructing lists of items within long-form content it is important to use semantically correct language and text formatting so your audience can understand what you’re trying to say. For example: *Use “-” or “+” for unordered list headers, as follows: +make sure that the first word in each bullet point matches the header+; do not capitalize the first letter in a sentence-like format unless they form sentences (bullets should be consistently formatted across all levels); indent bullets based on level using two commas between them. For example:
+Key Points? +Transitions! +Vocabulary Building ! ! Here are some additional bullet points. * **Begin each sentence with a capital letter and end it with either a period or semicolon if the sentence is more than one line long.* Beginning sentences (bullets) should be in complete, concise thoughts expressed as single-sentence paragraphs; punctuate them accordingly throughout to give your audience an idea of what you’re trying to say. For example: +A great way to start off writing any essay or article+ would be to introduce yourself – giving information about who you are so that readers can get some background on where they are coming from. *The first step when starting anything new is getting organized!
