ERROR: The 'run' command is only supported from within a workspace.

[Arturo Calvo]

I just installed the development environment for Magenta. When I run the following commands:

BUNDLE_PATH=/home/arturo/Downloads/basic_rnn.mag
CONFIG=basic_rnn


bazel run //magenta/models/melody_rnn:melody_rnn_generate -- --config=${CONFIG} --bundle_file=${BUNDLE_PATH} --output_dir=/tmp/melody_rnn/generated --num_outputs=10 --num_steps=128 --primer_melody="[60]"

I get error message:

The 'run' command is only supported from within a workspace.

What is wrong? I tried to install magenta environment as well (not development version) and when I run

source magenta activate

BUNDLE_PATH=/home/arturo/Downloads/basic_rnn.mag
CONFIG=basic_rnn

melody_rnn_generate \
--config=${CONFIG} \
--bundle_file=${BUNDLE_PATH} \
--output_dir=/tmp/melody_rnn/generated \
--num_outputs=10 \
--num_steps=128 \
--primer_melody="[60]"

I get error: 

melody_rnn_generate: command not found

Are you running the bazel run command from a directory in or below the Magenta project root?

Thanks for your response. That was the issue and seems to be working fine.

Regarding the second part (running it from the magenta non-development environtment), do you know what the problem is?

Thanks

No problem :) As for the non-dev magenta environment, what method did you use to install magenta (the automated install w/ the script provided or the manual install)? If you did manual, did you make sure to "pip install magenta" while inside of the correct conda environment (named "magenta")? Also what OS are you running?

Thanks Brannon! I installed it using:

curl https://raw.githubusercontent.com/tensorflow/magenta/master/magenta/tools/install.sh | bash

My OS is Ubuntu 15.04.

[Brannon Dorsey]

I wasn't able to get the install.sh script to work, but just reading over it it seems like it should be working for you and it is strange that it is not. You do have a magenta conda environment then correct ("source magenta activate" doesn't error right? And from there you can check your current env with "conda info --envs"). I installed conda with miniconda so my conda folder with all of my environments is in $HOME/miniconda2/. For me, melody_rnn_generate is in $HOME/minidonda2/envs/magenta/bin. Do you see the magenta scripts in your equivalent folder? If not, what do you see there?

Hello all,

I came across the same problem with magenta command not found. I posted this issue on stackoverflow as asked, because this is not supposed to be a help forum, but anyway... Here is the post:

Hi Brannon,

That's interesting. In the equivalent folder ($HOME/Apps/anaconda3/envs/magenta/bin) I see:

2to3  deactivate    openssl  python2    sqlite3

activate  easy_install    pip      python2.7    tclsh8.5

conda  easy_install-2.7  pydoc    python-config  wheel

c_rehash  idle    python   smtpd.py    wish8.5

No magenta scripts...

[Brannon Dorsey]

Hm... No tensorflow or jupyter either. Try activating your magenta environment with conda and then installing tensorflow, jupyter, and magenta with:

# Install tensorflow
TF_BINARY_URL="https://storage.googleapis.com/tensorflow/linux/cpu/tensorflow-0.11.0rc0-cp27-none-linux_x86_64.whl"

pip install --ignore-installed --upgrade $TF_BINARY_URL

# Install other dependencies
pip install jupyter magenta

[Arturo Calvo Devesa]

It is working perfectly now! Thanks a million Brannon.

No problem Arturo, glad you were able to get Magenta up and running :)

Gabriella, would this solution perhaps work for you as well?

Hello Brannon,

No, I am using a Mac.
