QUESTION
I have a varchar2 datatype field (lmp_date) that can return either null or what looks like a timestamp value. Changing the database data_type to DATE isn't a possibility, so now I'm needing to convert this to a date, but with the values this column returns, I'm having some problems.
Returned values for lmp_date =
null or 2021-06-11-00.00.00
Date format needed: MM/DD/YYYY
I've tried cast, convert, substr+instr to no avail
ETA - A couple example attempts (because there have been 10+:
select order_no, to_date(lmp_date) lmp_date from table_a - with error message of 'ORA-01861: literal does not match format string'
select order_no, to_date(substr(lmp_date, 1, instr(lmp_date, '00' -15))) lmp_date from table_a - since lmp_date has null value possibilities, this doesn't work successfully
select order_no, cast(lmp_date as date) lmp_date from table_a - with same error message of 'ORA-01861: literal does not match format string'
select order_no, to_date(lmp_date, 'YYYY-MM-DD') lmp_date from table_a - ORA-01830: date format picture ends before converting entire input string
There have been more attempts, this is all I can remember

QUESTION
Sorry if the question is silly but I am very noob with MYSQL and I am trying to update my table to clean and standardise the table. So I learned how to use the UPDATE command however I just want to check if there is a way to do the following:
UPDATE parse SET Stock = REPLACE(Stock, 'ETA%', 'Sold out');
Basically I want to have all the lines in my table that contain (or start with) ETA and change it to Sold out. The data is extracted from sites so Stock column has a bunch of crap like "ETA: 19-May" "ETA: in 5 days". I just want to change this all at once to "Sold out". Is there a way to do this?
I have also tried: UPDATE parse SET Stock = IF(Stock REGEXP '^ETA', 'Sold out', Stock);
but it didn't work. Any suggestion? Thanks !

QUESTION
I only found questions where people wanted to copy a dictionary to another depending on some keys but not for a list of dictionaries.
Lets say I have a List containing dictionaries
...ANSWER
Answered 2021-Jun-10 at 11:35You can use a dict comprehension to filter within a list comprehension for each dictionary. Basically check if the key is in your desired set, and if so, keep that pair in your newly generated dict.
QUESTION
I am training a DDPG agent on my custom environment that I wrote using openai gym. I am getting error during training the model.
When I search for a solution on web, I found that some people who faced similar issue were able to resolve it by initializing the variable.
...ANSWER
Answered 2021-Jun-10 at 07:00For now I was able to solve this error by replacing the imports from keras with imports from tensorflow.keras, although I don't know why keras itseld doesn't work
QUESTION
I have a list -cj1- with multiple data frames
...ANSWER
Answered 2021-Jun-06 at 20:40You can use the following solution. We use .x to refer to every individual element of your list. Here .x can be each of your data frames of which we would like to select only 2 columns c("individual","theta").
However, since only one of your data frames contains such column names I used keep function to actually keep only elements whose data frames contain the desired column name. Just bear in mind for this form of coding which is called purrr-style formula we need ~ before .x. So you use map function which is an equivalent to lapply from base R and use this syntax to apply whatever function on every individual elements (data frames here).
QUESTION
I have two play-once GIFs similar to the ones attached. I'd like to have the first GIF replace the original PNG upon mouseover, but even if someone removes the cursor from the image, finish playing the GIF so the last frame is in place before the mouseout GIF, which is the reverse of the previous one, replaces it and plays. I'd also like the original PNG to replace the mouseout GIF when it is finished playing, too. So, original > mouseover long enough to finish playing > mouseout long enough to finish playing > original.
I tried a javascript I found on here, and it worked to replace the images, but the mouseover GIF kept playing every now and again (even while the cursor was still on it) even though it is a play-once GIF (the script must have kept refreshing the GIF or something).
I'd keep the script in an external file as opposed to inline, of course. I know enough javascript to edit scripts, but not write them from scratch. jQuery is available, if needed.
Thanks for your help!

ETA: This is what I tried before, although this wasn't the final version of it since I was trying different things on that site that lets you try scripts on, and I think I had the timing set to 2888. I don't have the other script since I didn't save it:
...ANSWER
Answered 2021-Jun-06 at 06:06I guessed the animations to last about 3 seconds, but you can change that. Using setTimeout and a couple boolean values, we can delay the mouse on or off operation and queue up the next one. I also preload the images at the beginning to smooth out any loading flickers.
QUESTION
I'm training a convolutional autoencoder and noticed this warning:
...ANSWER
Answered 2021-Jun-05 at 14:41This could be the effect of accumulation with a low precision (e.g. FP16) data type.
Which data types are you using? And which algorithms?
From: https://docs.nvidia.com/deeplearning/cudnn/developer-guide/index.html
- Mixed Precision Numerical Accuracy
When the computation precision and the output precision are not the same, it is possible that the numerical accuracy will vary from one algorithm to the other.
For example, when the computation is performed in FP32 and the output is in FP16, the CUDNN_CONVOLUTION_BWD_FILTER_ALGO_0 (ALGO_0) has lower accuracy compared to the CUDNN_CONVOLUTION_BWD_FILTER_ALGO_1 (ALGO_1). This is because ALGO_0 does not use extra workspace, and is forced to accumulate the intermediate results in FP16, i.e., half precision float, and this reduces the accuracy. The ALGO_1, on the other hand, uses additional workspace to accumulate the intermediate values in FP32, i.e., full precision float.
QUESTION
I am trying to do some custom calculations in the custom loss function. But when I log the statements from the custom loss function, it seems that custom loss function is only called once (in the begin of .fit() method).
Example of Loss function:
...ANSWER
Answered 2021-Jun-04 at 12:18The loss function debug messages were printed only at the beginning of the training.
This is because internally your loss function got converted into tensorflow graph for the sake of performance, and the python print function only works when your function is being traced. i.e. it printed only at the beginning of the training which implies your loss function was being traced at that time. Please refer to the following page for more information: https://www.tensorflow.org/guide/function
Short answer: To print properly, use tf.print() instead of print()
And I would also like to know when the loss function is called/triggered?
After you use tf.print(), the debug messages will be printed properly. You will see your loss function is called at least once per step for getting the loss value and thus the gradient.

Install eta
If you prefer to operate via Docker, see the Docker Build Guide for simple instructions for building a Docker image with an ETA environment installed.
It is assumed that you already have Python installed on your machine. IMPORTANT: ETA assumes that the version of Python that you intend to use is accessible via python and pip on your path. In particular, for Python 3 users, this means that you may need to alias python3 and pip3 to python and pip, respectively. We strongly recommend that you install ETA in a virtual environment to maintain a clean workspace. Note that the install script supports flags that control things like (on macOS) whether port or brew is used to install packages. Run bash install.bash -h for more information. For Linux installs, the script inspects your system to see if CUDA is installed via the lspci command. If CUDA is available, TensorFlow is installed with GPU support.
Some ETA users are only interested in using the core ETA library defined in the eta.core package. In such cases, you can perform a lite installation using the -l flag of the install script:. Lite installation omits submodules and other large dependencies that are not required in order for the core library to function. If you use an ETA feature that requires additional dependencies (e.g., ffmpeg or tensorflow), you will be prompted to install the relevant packages.
If you are interested in contributing to ETA or generating its documentation from source, you should perform a developer installation using the -d flag of the install script:.
When the root eta package is imported, it tries to read the eta/config.json file to configure various package-level constants. Many advanced ETA features such as pipeline building, model management, etc. require a properly configured environment to function.
Get your feet wet with ETA by running some of examples in the examples folder. Also, see the docs folder for more documentation about the various components of the ETA library.
