Hi,

I am trying to read in parallel from a Tile-DB array in python and obtain the following Tile DB error:

`TileDBError: [TileDB::C++API] Error: Failed to create context`

I also wanted to have a look at your Tutorials on the problem, but found that all the links to the tutorials are not working properly on the following site.

> Everything you need to know about the TileDB core engine, APIs and integrations

Looking forward to any help.

Hi @brechtmann,

> I am trying to read in parallel from a Tile-DB array in python and obtain the following Tile DB error:

What method are you using to “read in parallel”? Note that TileDB will internally parallelize i/o operations over multiple threads within a given process (see [parameters](https://docs.tiledb.com/main/configuration-parameters) to control thread counts).

For documentation, the link you posted is to an old version of the docs – the current version is here: [TileDB Python Project — TileDB-Py 0.6.5 documentation](https://tiledb-inc-tiledb.readthedocs-hosted.com/projects/tiledb-py/en/latest/index.html)

And the tutorial/narrative docs are here: [Welcome to TileDB Embedded! - TileDB Embedded Docs](https://docs.tiledb.com/main/)

Best,
