Problems with let otree devserver run

I have a Python Code to conduct an experiment. To ensure that the Code is working smoothly I wanted to run a trial round via 'otree devserver', but I always get an AttributeError message and I am stuck here. Can anyone help me out?
I have downloaded the Code from GitHub and downloaded all required packages. I am using macOS, otree-5.10.2 and django-4.1.7. Here is my full traceback / error message:
Traceback (most recent call last): File

Pyspark databricks connect library issue

I am currently coding pyspark pipelines using databricks connect library. The steps I followed are given here. This library has been installed in a virtual environment.
When I try to execute this code
spark.read.load(path).first()
I get this error
<class 'TypeError'>, 'JavaPackage' object is not callable, <traceback object at 0x0000017AB70ECF88>

if self._sc._conf.get(self._sc._jvm.PythonSecurityUtils.USE_FILE_BASED_COLLECT()):
TypeError: 'JavaPackage' object is not callable
But when I am out of the virtual environment where I am using the pyspark library provided here, I am able to execute the same line and it gives me the output.
Can anyone please tell me where I am going wrong with this?

How to use dates in the yahoo_fin Python Package

I recently installed yahoo_fin and I tired the following example:
get_calls('NFLX' ')
It worked. I then tired the following:
get_calls('NFLX', '11/8/2019')
It failed. Here is what I got:
get_calls('NFLX', '11/8/2019')
Traceback (most recent call last):
File "", line 1, in
get_calls('NFLX', '11/8/2019')

ValueError: No tables found
I am using version 3.6.3 of Python and I am also using Spyder.
Am I doing something wrong? Do you think I have found a bug?
I updated my version of yahoo_fin. Not really sure it was out of date. I now get the following error messages when I run the command: get_calls("nflx", "1/31/20")
Traceback (most recent call last):
File "", line 1, in

It should work the way you have it.
from yahoo_fin.options import get_calls
get_calls("nflx", "1/31/20")
Are you using the most recent version of yahoo_fin? It should be (as of this writing) version 0.8.4. Another possible issue is that there could have been a problem with Yahoo Finance's page for that option chain at that particular time.

Can anyone help me?
I installed python 3.6.8, pytorch, torchfile, torchvision, etc., and I'm working on virtualenv.

vboxapi COM API not working

I have the virtualbox 5.0.10 Python sdk in my source root, but when I run my code the program will fail:
Traceback (most recent call last):
File "C:/Users/xiao/.PyCharm50/config/scratches/scratch", line 2, in <module>
mgr=vboxapi.VirtualBoxManager()
File "C:\Users\xiao\Desktop\test\vboxapi\__init__.py", line 1018, in __init__
self.platform = PlatformMSCOM(dPlatformParams)

return mapCLSIDToClass[clsid]
KeyError: '{7844AA05-B02E-4CDD-A04F-ADE4A762E6B7}'
Here is my code: (really simple, right?)
import vboxapi
mgr=vboxapi.VirtualBoxManager()
This program is buggy under Python 2.7.6, but runabble under Python 3.4.0.
Why? How can I fix that?
