Hi @timanix, I've replaced "|" symbols with ";" in my taxonomy file. I've checked for empty cells in these file, and it returns to me as a table with filled cells, so it's okay to me.

My feature table contains feature ids, also there is a "Taxon" collum but it works to use te `FeatureTable` with a taxonomy collum for other analysis in qiime2, so I think the point is specific with the taxonomy table.

I've runned the code again, and got the same error 😔

I've checked these discussions [here](https://forum.qiime2.org/t/typeerror-in-importing-silva-taxonomy/3879/13) and [here](https://forum.qiime2.org/t/gneiss-balance-taxonomy-error/4294/9). And it seems that maybe it's a formatting error in my taxonomy table.

I've runned `qiime metada tabulate` to obtain a .qzv file for my taxonomy table, and here is the result:

```auto
qiime metadata tabulate \
  --m-input-file Bacteria_taxonomy.qza \
  --o-visualization Bacteria_taxonomy.qzv

There was an issue with viewing the artifact Bacteria_taxonomy.qza as QIIME 2 Metadata:

  sequence item 0: expected str instance, float found

```

I don't know, but it looks like something is missing from the rows of my taxonomy table.
