instead of

Code:

echo $(python3 -c "import vosk; print('Vosk successfully imported!')")

just write

Code:

python3 -c "import vosk; print('Vosk successfully imported!')"

But anyway it is already there, "Vosk successfully imported!" was printed.

piotrbujakowski · 07-02-2024, 03:13 PM

That is strange, a problem.

Code:

echo $(python3 -c "import vosk; print('Vosk successfully imported!')")
bash: !': event not found

python3 -c "import vosk; print('Vosk successfully imported!')"
bash: !': event not found

Please try it again.
Configure.
Here is an example.

Code:

$ set -H
$ echo "print('Hello, World!')" | python3
-bash: !': event not found
$ set +H
$ echo "print('Hello, World!')" | python3
Hello, World!

piotrbujakowski · 07-02-2024, 04:30 PM

Look like that.

Still error in code.

Code:

set -H
echo "print('Hello, World!')" | python3
bash: !': event not found
set +H
echo "print('Hello, World!')" | python3
Hello, World!

NevemTeve · 07-02-2024, 10:14 PM

Please examine the lines you inserted: no error in the second half where `set +H` is used.

pan64 · 07-03-2024, 12:48 AM

it is the incorrect usage of " and '. For example in post #14

Code:

peter@peter-ThinkPad-P51:~$ source /home/peter/venv/bin/activate
(venv) peter@peter-ThinkPad-P51:~$ source /home/peter/venv/bin/activate
(venv) peter@peter-ThinkPad-P51:~$ python3 -c "import vosk; print('Vosk successfully imported!')"
bash: !': event not found
(venv) peter@peter-ThinkPad-P51:~$ echo $(python3 -c "import vosk; print('Vosk successfully imported!')")
bash: !': event not found
bash: !': event not found
bash: !': event not found
(venv) peter@peter-ThinkPad-P51:~$ echo $(python3 -c "import vosk; print('Vosk successfully imported!')")
bash: !': event not found
(venv) peter@peter-ThinkPad-P51:~$ python3 -c "import vosk; print('Vosk successfully imported!')
bash: !': event not found
(venv) peter@peter-ThinkPad-P51:~$ echo $(python3 -c 'import vosk; print("Vosk successfully imported!")')
Vosk successfully imported!
(venv) peter@peter-ThinkPad-P51:~$

Only the last one was working properly, all the previous attempts failed because of incorrect quotation. I understand it is not really straightforward, and can confuse people.
( ) ! have special meanings in shell, and in your case you need to use them as a regular char or string.

NevemTeve · 07-03-2024, 01:13 AM

Note: `set +H` could directly go into `~/.bashrc`.

Edit: not tested yet, but perhaps 'single quotes' prevents !events, while "double quotes" do not.

If so it is, the first should work, the second might fail:

Code:

echo 'We are single quoted here!'
echo "We are double quoted here!"

Mind you, single quotes within double quotes (or vice versa) have no special meaning (also they don't have to come in pairs).

Code:

echo '"This is single quoted too'
echo "'This is double quoted too"

piotrbujakowski · 07-03-2024, 02:39 PM

I have 2 catalogs:
- myenvy
- venv

I make back.

I copied both to self without replace and with replace.

Nothing change.

Is that same.

Code:

I make that again.

sudo chmod 775 -R /home/peter/venv/*
sudo chmod 775 -R /home/peter/venv/
sudo chmod +x -R /home/peter/venv/
sudo chmod +x -R /home/peter/venv/*
sudo chown peter -R /home/peter/venv/*
sudo chown peter -R /home/peter/venv/

sudo chmod 775 -R /home/peter/myenv/*
sudo chmod 775 -R /home/peter/myenv/
sudo chmod +x -R /home/peter/myenv/
sudo chmod +x -R /home/peter/myenv/*
sudo chown peter -R /home/peter/myenv/*
sudo chown peter -R /home/peter/myenv/

Code:

echo 'We are single quoted here!'
We are single quoted here!

echo "We are double quoted here!"
We are double quoted here!

Okay, I'll write this very slowly, to make it easy to undertand:

Do use command set +H e.g.:

Code:

source /home/peter/venv/bin/activate
set +H
python3 -c "import vosk; print('Vosk successfully imported!')"

piotrbujakowski · 07-03-2024, 02:51 PM

I do that.

Code:

source /home/peter/venv/bin/activate
(venv) set +H
(venv) python3 -c "import vosk; print('Vosk successfully imported!')"
Vosk successfully imported!

Regarding the error message: did it just appear out of blue sky, or you had done something before it?

pan64 · 07-04-2024, 01:54 AM

I think it is still the same issue again, you installed it using apt as a system-wide python module but you have started a venv and wanted to use it inside. You need to choose either this or that, but you cannot mix them.
If you have a venv, activate it and use pip install to install a module into it. Not as root, but as regular user.

piotrbujakowski · 07-04-2024, 05:41 AM

No always Python, see modules installed using apt.
Then I need instal using pip or pipx.

piotrbujakowski · 07-05-2024, 03:44 AM

So how fix that?

PS.

With Kaldi is a problem too.
I fight whole day without AI Chat Bot.
Everything from GitHub don't works.
