I cannot run “bob” by Spyder on a virtual machine with Linux (ubuntu 16) on a Windows 10 host

[Mohammad Saber]

Hello, 

I have a virtual machine with Linux (ubuntu 16) on a Windows 10 Host. I have installed Anaconda 3 (python 3.6) in virtual machine. I want to use “bob” in Linux because there is no Windows version.

I used Linux Terminal to install "bob". I followed the installation instruction on:

https://www.idiap.ch/software/bob/docs/bob/bob/stable/install.html

During installation, I saw an error after executing following code:

$ conda activate bob_py3

Therefore, I used following code instead:

$ source activate bob_py3

After then, I used the Gabor filter with an example explained here:

https://pythonhosted.org/bob.ip.gabor/guide.html

Problem: When I execute Gabor filter code in Spyder, “bob” package is not recognized by Spyder even though “bob” was already installed. The error message is as follows:

ModuleNotFoundError: No module named 'bob'

Hi,

Could you install bob 4 and try again?

Thanks,

I guess that your Spyder does not know the path of your anaconda installation. I am not familiar with Spyder, but you should be able to set your PYTHONPATH variable to point to your correct path, which should look somewhat like `[YOUR_ANACONDA_BASE]/envs/bob_py3/lib/python3.6/site-packages` (or something similar). If you don't find a way inside Spyder, you can try to go on the console and call:

$ PYTHONPATH=[YOUR_ANACONDA_BASE]/envs/bob_py3/lib/python3.6/site-packages spyder

This should solve your problem, independent of the bob version. Let us know if you have further issues.

Thank you. 

The problem was solved. I used a different terminal to call Spyder. I need to call Spyder in the same terminal that I created environment for Bob.
