            One of my assignment question - Just looking to keep it simple
            Asked 2022-Feb-01 at 15:05

            The program will take one argument, corresponding to one of the relations' keys. The program will print out the statement:

            John, I am your x

            Where x = the relationship.

            For example, if the argument is "Lisa", it should print "John, I am your sister"

            If the key is "Smith" you should instead print "No, I am your father"

            Here is my code:



            Answered 2022-Feb-01 at 15:01

            you did not import sys module, and you also need to specify the argument for the function Relation.

            As said in the comments, Conn can not be shared between threads, so in this case you would need to move the Pool handle, and get a connection from within the clusure itself:

            User R2D2 in the comments was correct; I needed to use the IP of the host machine, not the IP of the connecting machine. This makes sense, now that I know. Below is the working config - notice the IP listed is the IP of the Raspberry Pi, which is the same IP my dev machines will be pointing to in order to connect.

            Answered 2021-Dec-21 at 08:34

            First of all your question is missing important information. This includes the corresponding table! call from your schema.

            Now the guessing what could possibly cause this based on the information you provided:

            The error message indicates that you try to insert a NaiveDate into a Timestamp field. That's just something that is not supported as a timestamp expects a data and a time value, while a NaiveDate only provides a date value. You can see a list of out of the box supported type mappings for diesel in the documentation of each SQL type. For example for Timestamp here

            How to project PyBullet simulation coordinates to rendered Frame pixel coordinates using OpenCV?
            Asked 2021-Nov-15 at 22:50

            How can I convert an objects position in PyBullet to pixel coordinates & draw a line onto the frame using PyBullet & OpenCV?

            We would like to do this because PyBullet native addUserDebugLine() function is not available in DIRECT mode.



            Answered 2021-Nov-15 at 22:50

            After a lot of fiddling, I came to a solution. Playing with it for a while, I came to a point where it looked almost OK except for a rotation of the axes given by the yaw angle. So, I did a second call to computeViewMatrixFromYawPitchRoll but with the opposite yaw in order to compute the transformation for the axes. Unfortunately, I'm not sure about why this works... But it works! Note: base_pos, _cam_dist, _cam_yaw and _cam_pitch have been displaced into render() Note also: the up direction has been reversed too (don't ask why... :-) ) A pretty messy explanation, I must admit...
