As the title clearly describes the issue, I've been getting a FileNotFoundError error for a function call on Google Colab. You may find my script below. How can I resolve this issue? Any helps will be appreciated a lot.
def main():
# some code
if __name__ == '__main__':
main()
Error message:
FileNotFoundError Traceback (most recent call last)

I'm trying to run the following code for starting my google assistant with the raspbery pi:
googlesamples-assistant-pushtotalk --project-id my-dev-project --device-model-id my-model
But I get the following error:

Solve for me...
I'm trying to run pyspark using a notebook in a conda enviroment.
$ which python
inside the enviroment 'env', returns:
/Users/<username>/anaconda2/envs/env/bin/p
ython
and outside the environment:
/Users/<username>/anaconda2/bin/python
My .bashrc file has:
export PATH="/Users/<username>/anaconda2/bin:$PATH"
export JAVA_HOME=`/usr/libexec/java_home`
export SPARK_HOME=/usr/local/Cellar/apache-spark/3.1.2
export PYTHONPATH=$SPARK_HOME/libexec/python/:$PYTHONPATH
export PYTHONPATH=$SPARK_HOME/python/lib/py4j-0.10.9-src.zip:$PYTHONPATH
But still, when I run:
import findspark
findspark.init()
I'm getting the error:
Exception: Unable to find py4j, your SPARK_HOME may not be configured correctly
Any ideas?

EDIT:
If I run the following in the notebook:

spark = SparkSession.builder.getOrCreate()
I get the error:

I am a beginner to PyMOL and I am using it for my docking project. I have encountered errors using the Autodock/Vina plugin in PyMOL.
I was trying to carry out the set up for the grid and Error 1 occurred when I was clicking on the arrow that allows me to change the grid parameter x,y and z.
As for Error 2, it occurs when I tried to generate the receptor on the next page.
Under the log section, I also got a notice saying "Batch: prepare_receptor4.py -r C:\Users\User\Desktop\plugin-test\receptor.3ig7.pdb -o C:\Users\User\Desktop\plugin-test\receptor.3ig7.pdbqt -A checkhydrogen"
It would be appreciated if you would tell me what is missing or should be done to solve these errors.
I look forward to reading any of your replies and I thank you in advance,

I'm also encountering the same issue on Windows, try running a linux distro on vmware and make sure to install Pymol with support for Python 2.7 because the script is not compatible with Python3.

Any ideas how I might be able to fix this?
I am running a small StarCluster and using it to run an IPython Notebook. Every time I have an error in the code I'm writing in the notebook, I get the following error message added onto the end of the notebook's output:
Traceback (most recent call last):
File "/usr/lib/python2.7/logging/__init__.py", line 872, in emit
stream.write(fs % msg)
IOError: [Errno 32] Broken pipe
Logged from file ipkernel.py, line 427
Other than that, it seems to be running OK, but I don't know why that might be happening / how I can find out more about why it's doing that
