FYI, I just noticed that we are using also cassandra-test for the Python
DTests. git blame shows:
{code:java}
commit cb42c1a8d563ffd5cfab5d5c0ba3690d337958a3
install driver & ccm as editable eggs
{code}
No ticket was mentioned. And it seems in Cassandra; this was just mimicked for
the cqlsh tests in CASSANDRA-14951.
[~djoshi] and Ariel Weisberg , do you have any idea as to why this is used? (I
saw you worked on CASSANDRA-14951, so just checking in case you know more)
We may have wanted to use a special branch for testing. For CCM, that makes
sense, but I am not sure about the drivers at this point. CCM is just a test
framework, but I am not sure why we would not use a Python driver version.. or
at least I would expect it to be done just temporarily until a particular
release only.
[~absurdfarce] and [~jjordan] - maybe any of you know anything?

> Currently it's not possible to import rows with vector literals via {{COPY}}
> command.
> STR:
> * Create a table
> {code:sql}
> CREATE TABLE testcopyfrom (id text PRIMARY KEY, embedding_vector
> VECTOR<FLOAT, 6>
> {code}
> * Prepare csv file with sample data, for instance:
> {code:sql}
> 1,"[0.1, 0.2, 0.3, 0.4, 0.5, 0.6]"
> 2,"[-0.1, -0.2, -0.3, -0.4, -0.5, -0.6]" {code}
> * in cqlsh run
> {code:sql}
> COPY ks.testcopyfrom FROM data.csv
> {code}
> It will result in getting:
> {code:sql}
> TypeError: Received an argument of invalid type for column
> "embedding_vector". Expected: <class 'cassandra.cqltypes.VectorType(6)'>,
> Got: <class 'str'>; (required argument is not a float){code}
