No module named unusual_prefix_*

由 三世轮回 提交于 2020-12-08 14:08:20
问题 I tried to run the Python Operator Example in my Airflow installation. The installation has deployed webserver, scheduler and worker on the same machine and runs with no complaints for all non-PytohnOperator tasks. The task fails, complaining that the module "unusual_prefix_*" could not be imported, where * is the name of the file containing the DAG. The full stacktrace: ['/usr/bin/airflow', 'run', 'tutorialpy', 'print_the_context', '2016-08-23T10:00:00', '--pickle', '90', '--local'] [2016-08

问题 I am using pickle to save my trained ML model. For the learning part, I am using scikit-learn library and building a RandomForestClassifier rf = RandomForestClassifier(n_estimators=100, max_depth=20, min_samples_split=2, max_features='auto', oob_score=True, random_state=123456) rf.fit(X, y) fp = open('model.pckl', 'wb') pickle.dump(rf, fp, protocol=2) fp.close() I uploaded this model on S3 and I am fetching this model using boto3 library in AWS Lambda. s3_client = boto3.client('s3') bucket =

python 多进程

多进程 阅读: 222000 要让Python程序实现多进程（multiprocessing），我们先了解操作系统的相关知识。 Unix/Linux操作系统提供了一个 fork() 系统调用，它非常特殊。普通的函数调用，调用一次，返回一次，但是 fork() 调用一次，返回两次，因为操作系统自动把当前进程（称为父进程）复制了一份（称为子进程），然后，分别在父进程和子进程内返回。 子进程永远返回 0 ，而父进程返回子进程的ID。这样做的理由是，一个父进程可以fork出很多子进程，所以，父进程要记下每个子进程的ID，而子进程只需要调用 getppid() 就可以拿到父进程的ID。 Python的 os 模块封装了常见的系统调用，其中就包括 fork ，可以在Python程序中轻松创建子进程： import os print('Process (%s) start...' % os.getpid()) # Only works on Unix/Linux/Mac: pid = os.fork() if pid == 0: print('I am child process (%s) and my parent is %s.' % (os.getpid(), os.getppid())) else: print('I (%s) just created a child process (

Any idea with “OSError: [Errno 22] Invalid argument” in pickle.dump？

问题 Below is my code: In this code I am trying to split and normalize a ".p" file into files with different norms. However, it seems that the split is working but I cannot save them into ".p" files using pickle.dump. Any suggestion for this error? import numpy as np import pandas as pd import pickle import gzip # in this example tanh normalization is used # fold 0 is used for testing and fold 1 for validation (hyperparamter selection) norm = 'tanh' test_fold = 0 val_fold = 1 def normalize(X,

Dataset is given in a pickle file but it throws an error: ModuleNotFoundError: No module named 'pandas.core.indexes' import pickle import pandas dbfile = open(dataset loction,'rb') df = pickle.load(dbfile) I tried all the fixes given: Updated the pandas used df = pandas.read_picle(dataset location) Tried installing pickle using pip but getting this error C:\installs\WinPython-64bit-3.6.1.0Qt5\python-3.6.1.amd64>python -m pip install
