Python bamboolib has no attribute plugins

I'm trying to install bamboolib on a virtual env (py 3.6.8) but when I try to import the library on Jupyter lab I get the following error: module 'bamboolib' has no attribute 'plugins'.

Unable to Import Spacy or Download Models

I recently tried to install the spaCy module for Python 3.7. The installation looks like it runs successfully (shows no errors), but when I try to import spaCy, or when I try to install spaCy models, I get the error below. I'm totally lost; please help!

AttributeError: module 'tensorflow.python.ops.linalg.linear_operator_util' has no attribute 'matmul_with_broadcast'

I am trying to create my own PyEnvironment for TF-Agents.
However, this error keeps showing up:
AttributeError: module 'tensorflow.python.ops.linalg.linear_operator_util' has no attribute 'matmul_with_broadcast'
I have found out that this seems to be an issue with tensorflow-probability, but I have installed the version tensorflow-probability=0.7.0 recommended at
https://github.com/tensorflow/agents/issues/91
I have tried reinstalling and updating
tensorflow-gpu=2.0.0-beta1
tf-agents-nightly
tensorflow-probability=0.7.0
Here is a minimal code example:
from tf_agents.environments import py_environment
class myEnv(py_environment.PyEnvironment):
def __init__(self):
pass
def _reset(self):
pass
def _step(self, action):
pass
This is the full error message when running this minimum example:

_matmul = linear_operator_util.matmul_with_broadcast AttributeError: module 'tensorflow.python.ops.linalg.linear_operator_util' has no attribute 'matmul_with_broadcast'

Found it!
In order to use tensorflow-gpu with tensorflow-probability, one needs to install tfp-nightly
So pip3 install --upgrade tfp-nightly did the trick

To use 2.0.0beta1 requires tfp-nightly.

Weird behaviour with tweepy in Python?

I have python 2.7.9 on OS X (10.11). I have installed tweepy 3.5.0 and simplejson 3.8.1. When i write a program (IDE: textWrangler) for updating status of twitter account (by using tweepy) and run the program using command line it throws error on "import tweepy" in a program. However when i run the same code on python shell, it execute sucessfuly (without any error). Any suggestions or comments?

If I add this line:

sip.setapi('QString', 2)
ValueError: API 'QString' has already been set to version 1
anyone knows how to fix it?
Edit: If it will help, I see think that the problem is explained in the last column:
ValueError: API 'QString' has already been set to version 1
Edit: I tried changing API selection for QString and QVariant objects to Api #1,#2. didn't help.
Tried either to set the "Ignore API change errors" to true, didn't help.
Tried EST_TOOLKIT from 'qt4' to 'wx'.

It might be because spider itself uses the QT library and has already initialized it.
According to this http://pythonhosted.org/spyder/installation.html you could use PySide instead of PyQt4 (but i don't know if that's a configuation option or a fallback).
