问题 While doing GP regression in GPflow 2.0, I want to set hard bounds on lengthscale (i.e. limiting lengthscale optimization range). Following this thread (Setting hyperparameter optimization bounds in GPflow 2.0), I constructed a TensorFlow Bijector chain (see bounded_lengthscale function below). However, the bijector chain below does not prevent the model from optimizing outside the supposed bounds. What do I need to change to make the bounded_lengthscale function put hard bounds on

问题 I have the following data structure: fields = [{'key': 'ADDRESS1', 'value': None}, {'key': 'ADDRESS2', 'value': None}] Please note, the structure of this data is outside of my control. But I have to work with it. How would I go about updating the value "key" the Object where the key "key" is equal to, say 'ADDRESS1' , such that I would have the following after manipulation: N.B. The update has to update the value based off of the key , not the index of the object - as this is loosely defined.

问题 I am attempting to get Python.net (pythonnet) working on Python 3.7 and when running the setup.py it fails with the following error. I'm assuming that it has to do with a missing entry in the path lines but I coulnd't fine any reference to it. It's basically a pretty plain install of Python 3.7 on Windows 7. the pip install also fails with the same results. Does anyone have a suggestion on what path or file might be missing? PS C:\Users\user\pythonnet-master\pythonnet-master> python setup.py

问题 This question already has answers here : Python asyncio.semaphore in async-await function (2 answers) Closed 7 months ago . What is the best approach to deliver say 100k API calls using asyncio async/await with Python 3.7+ The idea is to use 100 tasks in parallel all the time? What should be avoided is: 1. To start working on all 100k tasks 2. To wait for all 100 parallel tasks to finish so new batch of 100 is scheduled. This example illustrates the first approach, that is not what is needed.

问题 What am I missing or doing wrong in the following python file using multiprocessing? When I run it, nothing happens and I have to restart the shell! def f(x): lo=0 for i in range(x): lo+=i return(lo) from multiprocessing import Pool def f_parallel(x1,x2,x3,x4): with Pool(processes=4) as pool: resulto_parallel=pool.map(f,[x1,x2,x3,x4]) return(resulto_parallel) f_parallel(1,2,3,4) Here is screenshot of what happens when I run it. And then after waiting a while I just restart the shell. 回答1:

问题 Here I grab the name and zip values from a different document; and store in variables: (works fine) Name = find_name.group(0) Then I simply want to search my excel file to find a match; where the Name text value is found, get row number(s): data = pd.read_excel(config.Excel2) row_number = data[data['Member Name'].str.contains(Name)].index.min() print(row_number) The above outputs the incorrect row number when printed, I cannot understand why. i.e. It does not print the row where the matching
