kandi X-RAY | Crossbow Summary
Crossbow is a multi-GPU system for training deep learning models that allows users to choose freely their preferred batch size, however small, while scaling to multiple GPUs. Crossbow utilises modern GPUs better than other systems by training multiple model replicas on the same GPU. When the batch size is sufficiently small to leave GPU resources unused, Crossbow trains a second model replica, a third, etc., as long as training throughput increases. To synchronise many model replicas, Crossbow uses synchronous model averaging to adjust the trajectory of each individual replica based on the average of all. With model averaging, the batch size does not increase linearly with the number of model replicas, as it would with synchronous SGD. This yields better statistical efficiency without cumbersome hyper-parameter tuning when trying to scale training to a larger number of GPUs. See our VLDB 2019 paper for more details. The system supports a variety of training algorithms, including synchronous SGD. We are working to seemlesly port existing TensorFlow models to Crossbow.

QUESTION
I'm developing a web game in JavaScript and I have a few arrays of objects. For some reason, I'm experiencing this problem: When I randomly select an object from an array:
...ANSWER
Answered 2021-Apr-20 at 16:30Your code is working fine and the variable itemToGive
is the object you think it should be. [object object]
is just some problem you're experiencing with string conversion. Run the snippet below
QUESTION
I've been learning Python off and on over the last 8 months. I understand the syntax for lists, tuples, sets and dictionaries. For fun I'm trying to create a character generator sheet for Dungeons and Dragons. I've got the program to randomly roll for my strength, charisma etc. Now I want to be able to ask the user, "What type of weapon do you want to use?" Get_Weapon_Choice, then pull up a list of that weapon type. I've tried creating a list weapon_Choices = ['Bow', 'Sword', ]. Then I created 2 other lists, bow = ['short', 'long', 'crossbow'] and swords = ['short', 'long'] I know how to get input from the user, but I don't know how to take that input and print the list, I'm printing the variable name.
chooseWeapon = input('What type of weapon would you like? Bow or Sword?')
How do I use chooseWeapon to compare to weapon_Choices to make sure they didn't enter something like Spells, then use chooseWeapon to print either the bow[] list or the swords[] list?
Do I need to use MySQL along with Python? and create tables and then search the tables instead of lists?
TIA! Don

QUESTION
I am seeking out the right collection type to achieve this result in C#. I am wanting to create a List of Items, from a couple of enum fields I've pre-specified.
- itemType
- itemMaterial
For every itemType I add, I would like for a new set of items to be created that follows this general pattern, (ripped from Runescape for ease of concept conveyance, don't come after me JaGex):
...ANSWER
Answered 2020-Sep-06 at 08:09No need for a specific collection. Just declare the item class and create all permutations.
Choosing a collection would be needed if you had specific requirements like quick access, fast iterations, one item pointing to another and more.

I have a Python list of strings. I want to do the regex search on each element, filtering only those elements where I managed to capture the regex group. I think I can do the regex search only once using the walrus operator from Python 3.8. So far I have:

...ANSWER
Answered 2020-Aug-10 at 17:39You are creating a new item object and returning that object so it is not keeping the older keys. I have modified your code logic.
QUESTION
I have an array of objects like this:
...ANSWER
Answered 2020-Aug-06 at 20:56Assuming the first name never has a space in it, you can use string.split
You can then use Array.prototype.shift to get the first element and join the rest back together.
For my example I changed the first name to have a last name with 2 words as a demonstration

You should have one linking table for alliances and one for oppositions.
QUESTION
Im trying to produce a very simple adventure text game and i tried to produce a minimal reproducible example in this case(my code may appear to be slightly long but i cant delete anymore or else it becomes difficult to understand).
The problem with my codes right now is that it wont proceed to go to the forest when the user is prompt to choose a choice = input("Go to the shop, go to the tavern, go to the forest: ").
And the other problem is that the user must enter tavern 2 times in order to proceed and after that it will show the error "dexterity not defined" at the line if dexterity >= 5: even though i have earlier listed it as part of the dictionary list...
...ANSWER
Answered 2020-Mar-01 at 11:39You have definied "dexterity" as part of "attributes" so you need to refer to is as attributes['dexterity'].

Install Crossbow
You can use Crossbow like any standard Java library. Please include the the jar files in your classpath. You can also use any IDE and you can run and debug the Crossbow component as you would do with any other Java program. Best practice is to use a build tool that supports dependency management such as Maven or Gradle. For Maven installation, please refer maven.apache.org. For Gradle installation, please refer gradle.org .
