Why do I get AttributeError: type object 'Placeholder' has no attribute 'loads', when running pyisntaller?

By -

I am using Python 3.10.6, pip 22.2.2 on Windows 11

I have a program which uses yfinance to grab stock data and sklearn.svr to predict stock data. I want to turn this program into a .exe file using pyisntaller. Pyinstaller finished and the .exe file is created but when I want to run it i get:

 File "PyInstaller\loader\pyimod02_importers.py", line 493, in exec_module
  File "requests_cache\__init__.py", line 7, in <module>
  File "<frozen importlib._bootstrap>", line 1027, in _find_and_load
  File "<frozen importlib._bootstrap>", line 1006, in _find_and_load_unlocked

  File "requests_cache\serializers\pipeline.py", line 44, in <listcomp>
AttributeError: type object 'Placeholder' has no attribute 'loads'

And when the pyisntaller is building the .exe file I get:

587 WARNING: Failed to collect submodules for 'pkg_resources._vendor.pyparsing.diagram' because importing 'pkg_resources._vendor.pyparsing.diagram' raised: AttributeError: module 'railroad' has no attribute 'DiagramItem'

So I think that the problem is because of matplotlib? I use it at the end to plot the predicted price.

The imports I am using on my program are:

import yfinance as yf
import requests_cache
import numpy as np
from sklearn.svm import SVR 
import matplotlib.pyplot as plt
import datetime as dt

I ran the program by moving into the right directory and than running:

pyinstaller --onefile -w stockPredictor.py

Spring Elasticsearch Operations

By -
Elasticsearch Operations Spring Data Elasticsearch uses two interfaces to define the operations that can be called against an Elasticsearch index. These are ElasticsearchOperations and ReactiveElasticsearchOperations. Whereas the first is used with the classic synchronous implementations, the second one uses reactive infrastructure. The default implementations of the interfaces offer: Read/Write mapping support for domain types. A rich query and criteria api. Resource management and Exception translation. ElasticsearchTemplate The ElasticsearchTemplate is an implementation of the ElasticsearchOperations interface using the Transport Client. @Configuration public class TransportClientConfig extends ElasticsearchConfigurationSupport {   @Bean   public Client elasticsearchClient() throws UnknownHostException {                      Settings settings = Settings.builder().put("cluster.name", "elasticsearch")....

Hibernate Search - Elasticsearch with JSON manipulation

By -
Elasticsearch with JSON manipulation Elasticsearch ships with many features. It is possible that at some point, one feature you need will not be exposed by the Search DSL. To work around such limitations, Hibernate Search provides ways to: Transform the HTTP request sent to Elasticsearch for search queries. Read the raw JSON of the HTTP response received from Elasticsearch for search queries. Direct changes to the HTTP request may conflict with Hibernate Search features and be supported differently by different versions of Elasticsearch. Similarly, the content of the HTTP response may change depending on the version of Elasticsearch, depending on which Hibernate Search features are used, and even depending on how Hibernate Search features are implemented. Thus, features relying on direct access to HTTP requests or responses cannot be guaranteed to continue to work when upgrading Hibernate Search, even for micro upgrades (x.y.z to x.y.(z+1)). Use this at your own risk....
