266 +You first have to **load the anaconda module:**
267 +
268 +(% class="code" %)
269 +(((
270 +module load anaconda/3
271 +\\
272 +)))
273 +

276 +(% class="code" %)
277 +(((
278 +source activate ~~/envs/tomopy
279 +)))
280 +
281 +\\
282 +
283 +~~/ takes you back to your home directory. In this case, the environment "tomopy" was installed in the home directory in the folder "envs". 
284 +
285 +\\
286 +
287 +now you can **start spyder**:
288 +
289 +(% class="code" %)
290 +(((
291 +spyder&
